CDO

Hello,

I have solar radiation grids giving total daily solar insolation in MJ/m2, from which I need to extract an instantaneous irradiance (W/m2) for a certain time of day. The calculations to do this require inputs of latitude, longitude and day of year.

Is there an operator that will return the grid X coord and Y coord in a calculation, so that I can do this calculation in CDO? I know of the undocumented muldoy operator which I can use to get the day of the year.

Thanks
David
