Direct Broadcast Reception Facility at SSEC

4.4 meter X-band antenna operational since Jan. 2001.

Receives Terra and Aqua routinely, day/night, all weather conditions.

Supporting customers with L0, L1, L2, and derived products since 2001, and National Weather Service since 2006.

EOS Direct Broadcast Activities at SSEC

Liam Gumley, SSEC UW-Madison


Objectives1. Routine and reliable acquisition and processing of direct

broadcast data.2. Creation of real-time products for operational customers.3. Development and distribution of DB processing software.

Accomplishments• Have acquired more than 30,000 Terra and Aqua passes.• MODIS, AIRS, and AMSR-E products are created automatically

and made available to the public via FTP, Web, ADDE.• IMAPP (funded by NASA) product generation software now in

use on every continent (credit: MODIS and AIRS Science Teams)• Active member of IPOPP Team.

Funding: NASA HQ, NOAA IPO, JPSS Project

Direct Broadcast Activities at SSEC



What is IMAPP?The International MODIS/AIRS

Processing Package is a suite of Linux software for generating products from Terra and Aqua direct broadcast data.

Released under open source license by SSEC with funding from NASA.

Based on NASA Science Team algorithms.

MODISNBAR


LANCE Products at UWWhich LANCE elements do you use?

MODIS.

Which data products do you download?MODIS L0, L1A, L1B 1KM, L1B HKM, L1B QKM, L1B GEO, MOD09_L2.

Are these products downloaded continuously or periodically?MODIS L1B continuously, others periodically.

Do you obtain the data from the ftp server or by subscription?FTP pull.

Do you use LANCE tools to generate derived products?No.



LANCE Applications at UWWhat applications are served by the LANCE data you download?

1. MODIS Image Processing System (MIPS): a global image

generation system for MODIS imagery

2. SatCam: an iPhone application for coordinated

satellite/ground observations of clouds

3. Volcanic Ash: Retrievals of volcanic ash loading and height

(Mike Paviolonis, NOAA)

4. Direct Broadcast algorithm testing: Simulate global direct

broadcast data to test algorithms for the DB community

Do you distribute LANCE-derived products to other users? Yes.

LANCE Latency

How critical is the 3-hour latency to your application(s)?

Not critical currently.

Would you application benefit from reduced latency and, if so, what latency would be desirable?

Volcanic ash global retrievals would benefit from reduced latency.

Can you identify new applications that are not presently serviced by LANCE if the latency could be reduced?

No.



Comments on the Present LANCE System(1 of 2)

Are there any features of the present system that you find particularly useful?FTP access.

Do you make use of the LANCE website, and, if so, what pages do you find particularly useful?No.

Have you received adequate information concerning the status of the system and system changes?Yes.



Comments on the Present LANCE System(2 of 2)

Do you have any criticisms of the present LANCE system? Have

you been particularly impacted by system downtime or

degraded service?

For real-time applications, delayed data arrival can cause

problems because the customer processing system may only

be sized to handle real-time rates (e.g., 10 MODIS granules

per hour). If data suddenly appears at higher rates because of

delayed processing, system must churn much faster to keep

up. Customer must be able to handle it (e.g., ignore data

more than 12 hours older than the current time).



Future Changes

• Do you have any suggestions for modifications or changes to the current system over the next 12 months?– Web services– Product images– MODIS NBAR real-time

• Can you suggest any longer-range changes?– Consider interfacing with DB sites users in a strategic

way– Everyone in the DB world receives the same packets

from the spacecraft…
