Hi Greg, I sent an inquiry off to SSEC regarding your MTSAT question yesterday and received the following answer last evening: I suspect that the NESDIS server is not running a current version of the MTSAT ADDE server. The fix for SS is in 2010.1 and later. Module: mtstaget2.for. I seem to recall that the ingested MTSAT segment files do not contain the information on which satellite, so we determine it this way: MTSAT 1R has a SUBLON = 140 MTSAT 2 has a SUBLON = 145 (as of 03/2010) A quick check of the 6.75 um water vapor imagery in the PUB dataset on the SATEPS ADDE server SATEPSANONE.NESDIS.NOAA.GOV shows that the image labeled as MTSAT-1R should be MTSAT-1R according to the guidance that SSEC provided: DATALOC ADD PUB SATEPSANONE.NESDIS.NOAA.GOV IMGLIST PUB/MTGLOB04I4 FORM=ALL Image file directory listing for:PUB/MTGLOB04I4 Pos Satellite/ Date Time Center Res (km) Image_Size sensor Lat Lon Lat Lon --- ------------- ------------ -------- ---- ---- ----- ----- ------------ 29 MTSAT-1R 30 OCT 13303 18:30:00 0 -140 Band: 4 6.75 um IR Mid-level Water Vapor 4.02 3.99 2750 x 2752 proj: 0 created: 2013303 190016 memo: MTSAT data from HRIT type:VISR cal type:BRIT offsets: data= 2816 navigation= 256 calibration= 0 auxiliary= 0 doc length: 0 cal length: 0 lev length: 0 PREFIX= 0 valcod: 0 zcor: 1 avg-smp: N start yyddd: 2013303 start time:183000 start scan: 0 lcor: 1 ecor: 1 bytes per pixel: 1 ss: 84 Resolution Factors (base=1): Line= 4.0 Element= 4.0 IMGLIST: done This would seem to indicate that MTSAT-1R is, in fact, the operational satellite and MTSAT-2 is not. Or, it indicates that SATEPS only has the MTSAT-1R data. What do similar IMGLIST listings show for the images in the MTS dataset?
