I would like to try converting the fraction of cloud cover data from the ERA5 hourly data on pressure level data set(https://cds.climate.copernicus.eu/cdsap ... b=overview). Since this is not surface level data but for the atmophere, I believe it should be added to the "atm" section of the cfg file.
I have consulted the ECMWF parameter database for the information of fraction of cloud cover and this is its information: And I have done the following modifications already.
Code: Select all
numatm = 7,
atmgrb = 'z','t','u','v','w','r','cc',
atmcat = 129 , 130 , 131 , 132 , 135 , 157 , 248 ,
atmnum = 129 , 130 , 131 , 132 , 135 , 157 , 248 ,
Even though Fraction of Cloud Coverage is different from TCLD, based on viewtopic.php?f=14&t=2129&p=6134&hilit=cloud+era5#p6134, I'm guessing that the conversion should be 100, since cc is also from 0 to 1.
However, I could not find the correct atmarl to use from https://www.ready.noaa.gov/hypub/flddesc.html.
Since there isn't an official field ID, can I just give it a random one?
My end goal of doing this is to just allow me to obtain the cloud coverage data along the trajectory endpoints through HYSPLIT's interpolation.
