Modifications in the era52arl.cfg file
Posted: April 19th, 2023, 4:40 pm
Thanks to the help from sonny.zin, I was able to compile the conversion program era52arl.
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.
But I am unsure what to add for atmcnv and atmarl.
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.
