<![CDATA[How does ECMWF or GFS separate in cloud layers their total cloud cover?]]>Hello, I would like to know how ECMWF or GFS separate in their algorithms the three cloud layers (low, medium, and high). I have read the work of Tiedtke (1993) for ECMWF but in GFS case I did not find anything. Thank you for your kind cooperation.

Regards,

Esther S.

For GFS, High-level is defined as above 440 mb level., low-level is defined
as below 680 mb, and mid-level is in between.
