Dear Su, We searched the Earthdata Search client for the granule ASTGTMV003N36E080.zip and downloaded it with no issues. We could not duplicate your issue with the data not being available. Please see attachment. LP DAAC does not support software and I'm not familiar with the Cygwin software. You mi...

Re: ASTER Data Download Cygwin Unable to Retrieve Data

After you create your account, you will also need to “authorize” the LP DAAC Data Pool application. Once the Data Pool application has been authorized, you will be able to download data.

Please let me know if you continue to have issues.
Kind regards,

Question: Could you help me to download ASTER L1T scenes with VNIR, SWIR and TIR bands?
Replies: 0

Could you help me to download ASTER L1T scenes with VNIR, SWIR and TIR bands?

ASTER Precision Terrain Corrected scenes are not produced if any of the bands in an AST_L1A granule fail during resampling. This typically occurs due to errors in the AST_L1A geolocation arrays. Additionally, since AST_L1T scenes are processed using AST_L1B processing algorithms, AST_L1T scenes are ...

What ASTER data would be best to use for mineral research?

Some minerals have distinctive shortwave infrared spectral signatures while others have unique thermal infrared emissivity spectral signatures. Therefore, ASTER Level 2 data products (AST_05, AST_07, AST_07XT, AST_08, AST_09, and AST_09XT) are suitable for mineral research. However, it is highly rec...

Re: AST_07XT - SWIR bands

ASTER acquisitions are submitted by approved users who have authorization to request bands to be turned on during acquisition. Each granule will have a metadata file that will have the bands collected. The Terra satellite was launched on December 18, 1999. ASTER SWIR detectors are no longer function...

Question: AST_07XT - SWIR bands
Replies: 3

Re: AST_07XT - SWIR bands

ASTER is a non-continuous on-demand sensor. Acquisitions must be requested by authorized users so this means ASTER data is not collected continuously and will have sporadic coverage. It is possible that not all bands were collected for each scene. You will need to check the metadata to view the band...

Re: parameters specifications for downloading MOD13Q1

Hi Paul, Sorry, but the ESI service that was used to do the processing for the Earthdata orders became very problematic and the server often crashed and lost orders, so that service was shut off for MODIS. Please take a look at AppEEARS as that will do much of what the Earthdata service did and more...
