Hi Gansham: In addition to what Tom stated, you can treat the wavelengths as coordinate variables (in addition to lat, lon, and time). If you want to capture the bandpass associated with the wavelengths, you can use attach a boundary variable to the wavelenght coordinate variable. Note that I am working the next generation GOES system and we have a dervied motion winds product that is very similar to yours. very respectfully, randy ---------------------------------------- From: "Tom Whittaker" <whittaker@xxxxxxxx> Sent: Tuesday, April 23, 2013 10:17 AM To: "ghansham sangar" <ghanshamsangar@xxxxxxxxx> Cc: "cf-satellite" <cf-satellite@xxxxxxxxxxxxxxxx> Subject: Re: [cf-satellite] Satellite Winds in CF conventions Hello Gansham... I would recommend that you use the "point" form and treat each unique location as a separate "record", using the form defined here: <http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.6/cf-conventions.html#i dp8294224> using a 'featureType="point" ' global attribute (see: <http://www.unidata.ucar.edu/software/netcdf-java/reference/FeatureDatasets/ CFpointImplement.html> Best wishes, tom On Mon, Apr 22, 2013 at 9:03 PM, ghansham sangar <ghanshamsangar@xxxxxxxxx> wrote: R/Sir I want to understand how to pack satellite wind data coming from different channels into product. the winds data is pretty much a point data. Lat,Lon, U_COMP, V_COMP, WS, WDIR....... And in addition we have winds for three different channels: VIS, IR and WV. So the winds from the different channels may not be co-located. All have different lat/lon associated with them. So what could be the best way to pack them within a product as per the conventions. If we have some sample products, then it will be really appreciated. regards Ghansham _______________________________________________ cf-satellite mailing list cf-satellite@xxxxxxxxxxxxxxxx For list information or to unsubscribe, visit: http://www.unidata.ucar.edu/mailing_lists/ -- Tom Whittaker University of Wisconsin-Madison Space Science & Engineering Center (SSEC) Cooperative Institute for Meteorological Satellite Studies (CIMSS) 1225 W.
