Hi Clay, I assume that you are the same Clay Davenport that I used to interact with at UVa? If yes, I trust things have been good for you at NOAA! re: > The reason you are having so much trouble reading the image file you are > grabbing is because it is not a blended TPW file, but a blended Rain Rate > file - that's the "RRdata" in the path name. Ah Ha! This makes complete sense now! re: > It uses the same brightness to > rain rate conversions as the AMSU and SSMIS products used by SAB. Do you happen to know what the BRIT -> RR relationship is? If no, I can search on the web. re: > I don't believe we distribute the blended TPW through the satepsanon > server. The SATEPSANONE.NESDIS.NOAA.GOV ADDE server has dataset definitions for both BLTPW and BLPWTM, but neither dataset has any elements DATALOC ADD PUB SATEPSANONE.NESDIS.NOAA.GOV DSINFO IMAGE PUB ... BLPWTM 20 Blended TPW Time composite BLTPW 20 Blended TPW composite ... re: > We do distribute it through our ADDE PLR server, as PLR/BLTPW_GPS, > and that is on the 176-251 = 0-75 mm scale. Thanks for pointing this out. I have access to the PLR ADDE server (SATEPSDIST4E.NESDIS.NOAA.GOV); I am able to check BLTPW type images: DSINFO I PLR Dataset Names of Type: IMAGE in Group: PLR Name NumPos Content ------------ ------ -------------------------------------- ... BLPWTM 20 Blended TPW Time composite BLTPW 20 Blended TPW composite BLTPWANMCIRA 25 24 hrs Blended TPW Anomaly from CIRA BLTPWCIRA 25 24 hrs CIRA Blended TPW Composite BLTPW_ANOM_C 25 24 hrs Blended TPW Anomaly from CIRA BLTPW_GPS 25 24 hrs Blended TPW composite with GPS data BLTPW_PCT 25 24 hrs Blended TPW Anomaly composite ... I see images in BLTPW_GPS and BLTPW_PCT, but no others; these two datasets may are useful, but not sufficient. re: > Since I'm not sure what you have access to, let me know what you need and > I'll figure out a way to get the data where you can get it...within the > constraints I have to deal with here. Question: - would it be possible to get some example GINI images from the BLTPW_GPS and BLTPW_PCT datasets? These would be most helpful! Comment (for you AND for SSEC MUG folks who are CCed on this exchange): - one of the challenges for creation of valid calibration blocks is that the band number for the BLTPW_GPS images is the same as for the BLTPW_PCT images Cheers, Tom -- **************************************************************************** Unidata User Support UCAR Unidata Program (303) 497-8642 P.O.
