2 Overview of the Interfaces

2.1 Naming Convention

2.1.1 Interfaces Identification namespace

The following convention has been adopted for the external and internal interface naming:

<EI | II> + <_> + <Id Subsystem> + <_> + <Prog_number>

where

EI or II = <EI> in case of external interface, <II> in case of internal interface

Id Subsytems = Identifier of the involved subsystem, according to the following

specification:



Issue: Version 1.1

Date: 20/06/2008

Page: 23/149

PR: Precipitation Subsystem;

SM: Soil Moisture Subsystem;

SP: Snow Parameters Subsystem;

HV: Hydro Validation Subsystem;

OM: Offline Monitoring Subsystem.

Prog_number = progressive number for the interfaces of the specified type

belonging to the specified subsystem

e.g.: EI_PR_23 is the identifier of the external interface n.23 of the Precipitation

Subsystem.

e.g.: II_SM_14 is the identifier of the internal interface n.14 of the Soil Moisture

Subsystem.

2.1.2 Interface Data namespace

The following convention has been adopted for the external and internal exchanged data

identification:

<ED | ID > + <_> + <Source ID> + <_> + <Prog_number>

Where

ED or ID = <ED> in case of external interface data, <ID> in case of internal

interface data

Source ID = a <short name> as source identifier,in case of external interface data.

In case of internal interface a notation like <id1_id2> specifying the two involved

subsystems.

Prog_number = progressive number for the interface data of the specified type

belonging to the specified subsystem

e.g.: ED_METOP_11

is the identifier of external interface data n.11 of the Metop Satellite data source.



Issue: Version 1.1

Date: 20/06/2008

Page: 24/149

e.g.: ID_PR_OM_6

is the identifier of internal interface data n.6 exchanged between the Precipitation

Subsystem and the Offline Monitoring Subsystem.

For specification of data acquired from satellite data sources, the following notation is

used:

<SatelliteName-SensorName>

e.g.: MetOp-MHS.

2.2 H-SAF External Interfaces

2.2.1 Introduction

External interfaces involve at least one H-SAF external actor (system or user not

belonging to the H-SAF context) and at least one H-SAF internal actor (subsystem,

component or subcomponent).

Interfaces among external users without the participation of an H-SAF element are not

classified as “H-SAF External Interface”, even when exchanged data is produced inside H-

SAF system and/or disseminated through an H-SAF component.

The external interfaces are here classified into two groups:

Data Acquisition interfaces: have as external actor a source data (Satellite data

sources) or a system producing input data for the H-SAF generation chains. The

data flow starts outside and goes toward internal element of H-SAF.

Data Distribution interfaces: have as external actor a user or a system to which

products and reports generated inside H-SAF are sent. The data flow starts inside

H-SAF and goes towards external actors.

2.2.2 Data Acquisition Interfaces Overview

Here are detailed the external interfaces that H-SAF requires in order both for acquiring

input data and for disseminating products to users during operational phase (Table 1).

Offline Monitoring Subsystem has no data acquisition interfaces.

External actor can be an Organization as well an Institute. Internal actor is an H-SAF

component.

Table 3 H-SAF External Data

2.3 H-SAF Internal Interfaces

2.3.1 Introduction

Internal interfaces involve components and/or sub-components belonging to H-SAF

subsystems. The two items involved in a specified interface can belong to the same

subsystem (thus it is a subsystem internal interface), or they can belong to different

subsystems (interface regarding H-SAF internal data distribution or internal data

exchange).

Subsystem internal interfaces related to very simple data flows, not worth having a

detailed specification, are omitted in present document. These cases are usually

component/subcomponent internal data flows, since they involve members of the same

sub-component not having a deeper connotation in the model (they have not been

represented by sub-sub components).

An example of such case is the Snow Status Model internal sending, as a task achieved

by SP-GC1-PG sub-component during the SP-GC1 product generation: an SP-GC1-PG

internal actor sends via email the updated model to another SP-GC1-PG internal actor.

Interfaces involving different subsystems’ components are treated once inside one of the

two subsystem internal interfaces specification: they are not repeated for both subsystems.

As an arbitrary rule, the interface specification is given for the source component, which is

the component from which the data flow starts.

An example of such case is the Hydro Validation reports sending by HV-VPR component

of Hydro Validation Subsystem to OM-CEN component of Offline Monitoring Subsystem.

Since there is obviously only one interface (II_HV_20), it is specified in one section of the

document (section regarding Hydro Validation Subsystem internal interfaces).

As explained in the introduction (see 2.3.1), uninteresting internal interfaces are omitted.

For Snow Parameters Subsystem, omitted interfaces are those related to the SP-GC1-PG

internal sending of Models aimed to the product generation, via email. Specifically:

Model for Snow Status (exchanged between TKK/LST and SYKE)

Model for SCA with flag for snow status (exchanged between FMI and SYKE)

Model for SWE mapping (exchanged between TKK/LST and FMI).

3.3 Snow Parameters Subsystem Data Flows

3.3.1 Description

The subsystem data flows start with the acquisition of raw data from satellites, performed

by SPG-GC1 and SP-GC2 components through specific interfaces. All data is pre-

processed respectively by the Finnish and Turkish pre-processing subcomponents and

then passed to the relevant generation chains. A merging phase between Finnish and

Turkish products is managed by the Finnish generation chain. Validation process of all

products can lead to the rejection of those not considered validable: in these cases the

data flow ends and the subsystem turns again into its “ready to receive” status.

Validated products are quality flagged and then disseminated.

3.4 Hydro Validation Subsystem Data Flows

3.4.1 Description

This subsystem can be abstracted as a black-box receiving as input the H-SAF products

and providing hydro validation reports as output.

The data flow consists of the product transformation into an item adapted to be processed

by the models. Once the models run on the product just pre-processed, the reports are

produced and immediately sent to the Offline Monitoring Subsystem.


The following data is managed by HV subsystem:

Precipitation products

Snow Parameters products

Soil Moisture products

Hydro Validation reports


The following State Diagram gives evidence of the main states of the Hydro Validation

Subsystem. Each time a product is available, as soon as it is produced by the generation

chains, this product is acquired by the subsystem. The acquisition is the first action starting

the tasks of the subsystem, followed by the pre-processing and the validation of the

product acquired. The last but most important activity of the Hydro Validation Subsystem is

the report generation. Each report is sent to the Offline Monitoring subsystem for H-SAF

internal dissemination.

3.5 Offline Monitoring Subsystem Data Flows

3.5.1 Description

This subsystem achieves the task of centralizing the main objects of the H-SAF system

(the generation chains products) in order to be maintained and distributed in an offline

mode.

This aim lets the same subsystem monitoring the functionality of each H-SAF subsystem

and component in a central mode, with the result of the production of performance reports

for each products managed.

An exhaustive information system is managed by Offline Monitoring Subsystem in order to

maintain products as well as the performance reports.

Its crucial position inside the system carries out also the functionality of dissemination to

the external users through UMARF client, as well as an internal distribution of reports

among the generation chains.


Precipitation Products, Snow Parameters Products, Soil Moisture Products, Hydro

Validation Reports, Performance Reports.


Events starting each interface process are:

Reception of new products;

Reception of new reports.

If a new performance report is available, it is acquired and archived by Offline Monitoring

Subsystem. If a product is available in input, the acquisition component of OM subsystem

starts the acquisition process followed by these two tasks:

product archiving into the central archive

product’s performance report generation and archiving

Ingestion Process in charge of receiving products from each

generation chains and receiving hydro validation reports

from Hydro Validation Subsystem. This process achieves

the first phase of the centralization activity.

Archiving Archiving interface process consists of storing data received

from the other subsystems (products and hydro validation

reports) into a central archive. This process achieves the

second phase of the centralization activity.

Performance Reports

Generation

This is the process in charge of generation performance

reports for each product received from the generation

chains. It starts as soon as the ingestion process ends its

task.

Catalogue Updating Offline Monitoring Subsystem frequently receives products

and reports and with the same frequency it archives these

data into a central archive. The Catalogue Updating process

is in charge of maintain a directory of all products and

reports available in the central archive, ready to be

disseminated to the external users.

Orders Management All the tasks concerning the reception and management of

orders from users through UMARF client is achieved by this

process. Each order is examined before confirming or

rejecting it to the user. The Orders Management process

export products from central archive and send it

Archive Management It is in charge of accessing to the central archiving in order

to provide products and reports respectively to the users

whose request has been scheduled by order, and to the

generation chains after generating products.

Reports Dissemination It manages the interface between Offline Monitoring

Subsystem and the generation chains, with the aim of

providing to the chains the performance reports after each

product made available.

Product Dissemination This process manages the interface between Offline

Monitoring Subsystem and external users, through the



Issue: Version 1.1

Date: 20/06/2008

Page: 65/149

UMARF client. Each order coming from users is passed to

the Orders Management process. Catalogue is sent by this

process, as well as the products required.

This section provides a technical specification of each interface (external and internal),

detailing its main elements, in terms of:

Type: the interface type for the data exchanging. E.g.: File, Email, etc.

Support Type: the transmission mean to vehicle data. E.g.: Radio, Electronic, etc...

Protocols: the interface protocols. E.g.: FTP, TCP/IP etc.

Source Component: component involved in the interface data flow as a source of

the data/process flow. Location of the component is also provided, in terms of

institute or organization physically hosting the component.

Destination Component: component involved in the interface data flow as a

destination of the data/process flow. Location of the component is also provided, in

terms of institute or organization physically hosting the component.

Transmission delay: the delay produced by the interface as the time spent by the

data to travel from the source to the destination point of the interface. E.g.: seconds,

minutes, RT (Real Time), NRT (Near-Real-Time) etc...

Mean Frequency: mean frequency of the activation of the interface’s data flow.

E.g.: 250 / month, asynchronous, etc...

Size: size of the data passing through the interface. E.g.: Kbytes, Mbytes to

GBytes, etc...

Trigger Events: events causing the activation of the data flow and the interface

processes related to this data.

H-SAF System Engineering is compliant to the latest ECSS standards.

ECSS standard founding principles have been adopted into H-SAF Engineering, such as

the tailoring concept and the strict relationship between Software Engineering and System

Engineering.

These principles are particular meaningful in the H-SAF context, since H-SAF is a complex

system into which the software layer is just one of many different layers building up the

heterogeneous set-up.
