CDO

Hi,

I want to use the ml2pl operator. In the user guide it says

The input file should contain the log. surface pressure or the surface pressure

In my ECMWF grib files I have only the log. surface pressure, and the CDO does not work, complaining that it expects the surface pressure.

Can the CDO use the log. surface pressure or not? And if not, can it be "tricked" to use it by some conversion?

Thanks for your help

Roger
