Re: How to download global VIIRS L1A and geo data?

Hello Sean, Thank you for your attention and reply. Indeed, I could generate VIIRS GEO files using the "geolocate_viirs" tool under OCSSW in Seadas. However, when I converted VIIRS L1A data with that GEO files to L1C data, the converted L1C data were different from that converted from the ...

However, if I do not register for the samoa access, I cannot get the DEM files. In addition, I could generate Geo files without DEM files usin...

Re: How to download global VIIRS L1A and geo data?

Hello Tommy, Thank you for your reply. I tried to download DEM files for VIIRS from the NASA OBPG server, but I did not figure out how to register for "samoa.gsfc.nasa.gov". So could you tell me how to register for this server? In addition, I think it is easier to use your first approach. ...

Re: How to download global VIIRS L1A and geo data?

Hello Tommy, Thank you for your reply. The URL I used to download VIIRS L1 data did not include L1A. For example: https://oceandata.sci.gsfc.nasa.gov/cgi/getfile/requested_files_1.tar?h=ocdist305&p=/data1/a000d322b38f2e67/requested_files All the L1A files are in the folder of requested_files_1.t...

Re: OCSSW installation

Hello Xuanyang, Thank you very much for your help. Before I saw your message, I installed OCSSW successfully by a different method which was to install it from seadas software. So I did not try your update code. Hopefully, it will work. It seems that somewhere in the code is wrong. In addition, I ca...
