Re: related to TRMM (2A12) vertical profile data

No, only a recipe I put together few years ago to extract the profile data from 2A12 (long, but no programming is needed): Note: you could bypass Step 1 in this example since I got the pixel location already. Step 1. Obtain the TMI orbit scan and pixel info. You can use PPS THOR, http://pps.gsfc.nas...

Re: related to TRMM (2A12) vertical profile data

Dear TRMM user, Thank you for your inquiry about 2A12. For 2A12, all hydrometeor profiles over land are set to missing in V7 2A12 due to large uncertainty (see the FAQ below): https://disc.gsfc.nasa.gov/information/faqs?keywords=2a12&title=In%20TRMM%20V7%202A12,%20why%20are%20there%20no%20hydrom...

Re: a question about 3A GPM_DPR

Dear GPM user, Thank you for your inquiry about GPM_3DPR. The number of heights above the earth ellipsoid: 2, 4, 6, 10, and 15 km is 5 for both grids (G1: 5 deg. and G2: 0.25 deg.), based on the file specification document, ftp://gpmweb2.pps.eosdis.nasa.gov/pub/GPMfilespec/filespec.GPM.pdf The verti...

Re: TMPA products

We discourage downloading large datasets such as TMPA in ASCII format. The download will likely be much slower and may take much more network bandwidth, and storage, especially for large subset regions. All TMPA files at GES DISC are internally compressed, which is seamless to the user, and thus the...

Re: TRMM and GPM

The projection used is, geographically, the Equirectangular projection, and the datum is WGS84.

When import the data into GIS software (e.g., ArcGIS, Erdas/Imagine, ENVI), select the global WGS84 "Geograhic" coordinate system as spatial reference/projection info.
