OVERVIEW |
|
|
The A-Train Data Depot (ATDD) has been developed to process, archive, allow access to, visualize, analyze and correlate distributed atmospheric measurements from A-Train instruments. The ATDD portal provides easy on-line data access and services for science, applications, and educational use so that users get exactly the data they want, and not large files of data which would take much time and effort by individuals to be co-registered and refined.

Unlike Hurricane Katrina (2005), the recent Hurricane Gustav made the landfall as category 2, and spared New Orleans by passing 66 miles west of it. Katrina stayed as category 5 for about 15 hours,with pressures as low as 902 mb, and was of category 4 just before making landfall. This Google Earth KMZ file shows MODIS/Aqua image of Gustav from September 1, and contains Gustav's (red line, past and projected as of Sep. 2) and Katrina's tracks (black line) for comparision. MODIS data are from the NASA's Direct Readout.

A-Train Data Depot:
- Facilitates the visibility of participating A-Train missions.
- Provides data previews through GIOVANNI.
- Provides MODIS/Aqua subsets collocated with CloudSat and MLS.
- Is a convenient access point to data from A-Train instruments.

06.17.08 - A-Train reconfiguration finalized
The re-phasing of the Aura platform, that left the satellite drifting forward and closer to CloudSat and CALIPSO, has been finalized. Thus, as of May 2008, the MLS and CloudSat footprints are within 3-4 km in the lateral (zonal) arc distance at the Equator crossing, and 2-3 sec apart.

| 02.12.08 - Aura re-phasing continues as planned; MODIS MLS-collocated subset from A-Train Data Depot discontinued.
In accordance with the decision to reconfigure the A-Train formation, the re-phasing of the Aura satellite is progressing as planned. The immediate substantial effect of this maneuver is that the footprint of the MLS retrieved column drifts away from the MODIS/Aqua nadir.
