A-Train Data Depot

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.

On September 15, 2009, the A-Train formation happened to fly over the super-typhoon Choi-wan. Just one such event can yield enormous amounts of data of various science content and format from the diverse A-Train sensors.  Plotting quickly  retrievals like cloud profiles, cloud top temperatures, rain rates,  water vapor content, etc.,  for head-to-head previews, is the strength of the Giovanni  web tool. An example of the  tool output is shown on the left. Apart from these 2-dimensional plots, Giovanni provides KMZ (GoogleEarth) format of the vertical atmospheric profiles (far left). Thus, it is now possible to combine horizontal and vertical data layers in one three-dimensional object, and preview data from different geometrical aspects. The far left plate shows a snapshot from a GoogleEarth KMZ file where CloudSat profiles are pictured together with MODIS/Aqua true-color image, and AMSR-E rain rate.
