Hi, First, I have to say that I am by no means a nedcdf nor cf expert... I also have to say that I am very happy that Eumetsat decided using netcdf4, especially with cf conventions. But here are some things that I was wondering looking at a Seviri file: - - Why are southMostLine, eastMostPixel, northMostLine, westMostPixel, and numberOfChannels dimensions and not attributes ? - - How would you deal with the inclusion of the HRV channel ? - - Are the longitudes and latitudes values different from what a "vertical perspective" with right parameters would provide ? If they do, why ? If they don't, why not include a grid-mapping definition ? - - On the cf-satellite list, we have long been discussing "band"s. Did you consider using those ? - - Did you consider grouping channels in 3d arrays instead of having them separated ? - - Could you provide in the file calibration coefficients needed to convert radiances to reflectances and brightness temperatures ? Thanks a lot for making this data available !
