FTSBlock2.0TTOPathForward

• Block 2.0 Changes for FTS

– Inputs from CGS changing with Block 2.0: • CGS Extranet Web Server

• CGS Support Node content with Block 2.0

– Internal changes to FTS:

» Checksum calculation differences (from CRC to SHA 384)

» Possible directory changes

– Output:

• University of Wisconsin and GSFC Direct Readout Lab (DRL) using FTS Web Portal instead of NPP External Mission Support Data Server (E-MSDS) for accessing Ancillary and Auxiliary Files
