Mesoscale Alpine Programme (MAP)
• MAP: 1st WWRP RDP • Phase 1: Preparation, 1993 – 1999• Phase 2: Special Observing Period, Sep – Nov 1999• Phase 3: Analysis, ongoing (formally ended in Sep 2006)
• MAP D-PHASE:• Phase 4 of MAP: Demonstration• Focus:
• heavy precipitation …• … and hydrology
• Endorsed as 2nd WWRP FDP in Oct 2005• D-PHASE: Demonstration of Probabilistic Hydrological
and Atmospheric Simulation of flood Events in the Alpine region

D-PHASE
Approach: Distributed real-time end-to-end forecasting
system, including• (limited-area) probabilistic forecasting, both for
atmospheric and hydrological processes• high-resolution deterministic modelling & nowcasting• centralised visualisation of model data and alerts • forecasters and end users• evaluation, objective and subjective

International collaboration: COPS
• Joint data archive• data (atmospheric and hydrological models, nowcasting
tools, observational data) & data derived products• alerts• feedbacks
• Generation of atmospheric model products (‘quicklooks’)
• Visualisation of atmospheric model products

Atmospheric model data: List of variables to be stored
TIGGE (http://tigge.ecmwf.int) – inspired:• single level fields (up to 41 per output cycle)
• e.g., 2m air temperature, Total precipitation: grid-scale only, Total column cloud ice (ice water content), Surface short wave radiation (outgoing), Convective Inhibition, …
• upper-air fields (up to 11 variables)• e.g., temperature, cloud water, graupel, …• on up to 9 pressure levels• on (some or all) model levels
For details, check here (or in the COPS/GOP/D-PHASE Common Data Implementation Plan!)

Atmospheric model data: List of variables to be stored
Different output for COPS and MAP D-PHASE domains
• ensembles (D-PHASE domain)• single level fields (22, 3-hourly)• upper-air fields on pressure levels (54, 3-hourly)
• deterministic driving models (D-PHASE domain)• single level fields (41, hourly)• upper-air fields on pressure levels (54, hourly)
15 Status of D-PHASE Marco Arpagaus ([email protected])
Atmospheric model data: List of variables to be stored
• high-resolution deterministic models• single level fields (41, hourly), upper-air fields on
pressure levels (54, hourly), and upper-air fields on model levels up to 4000m above msl (180, hourly) for D-PHASE domain
• additionally, but for COPS domain and 1.6.2007 – 31.8.2007, only
• single level fields (41, every 15 minutes)• upper-air fields on (9) pressure levels (99, every 15
minutes)• all upper-air fields on (60) model levels (660, every
15 minutes)

Output format: GRIB1 (details to be specified by WG-DI)
Estimated storage space:
• ensembles 311 GB• PEPS and micro-PEPS 184 GB• deterministic driving models 337 GB• high-resolution models (D-PHASE domain) 8461 GB• high-resolution models (COPS domain) 7456 GB

Atmospheric model data: Visualisation
• Generation of atmospheric model products with a common plotting software (which will be provided by COPS) to ensure uniform ‘look and feel’. Options:
• Generation on CPU and disk at M&D (triggered by COPS or model providers).
• Generation on computational environment of model providers.
List of products to be defined …• If possible, use of common visualisation tool and/or
platform.

D-PHASE: Milestones
• Completion of MAP D-PHASE Implementation Plan (and COPS/GOP/D-PHASE Common Data Implementation Plan) as soon as possible, preferably until the MAP D-PHASE Meeting in Vienna (6 – 8 Nov 2006), e.g., • specification of output variables, output format, model
products, visualisation platform, and data flow• Dry run: 26.2 – 2.3.2007
• data archive up and running• model output ready• generation of model products implemented• data flow established• visualisation platform set up
