MOD11A1 - MODIS Land Surface Temperature Product
6/16/2009 - Peter and Karl meet re acquiring and projecting Sierra Nevada Data
Version 5 data seems to be complete on LPDAAC datapools (and ftp) Data Size is 3 to 6 MB per granule. For Sierra, 3 granules, 9 years, 365 days = 30 to 60 GB Projected data is similar in size. Total Space between 60 and 120 GB
