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

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

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
