Question about Input Net Radiation Dataset

[KaixuanDai]

I've noticed that the input data for net radiation, labeled as lwnet_gswp3-w5e5_obsclim_1901-2019.clm, is included in the input.cjson file. However, I couldn't locate this specific climate variable within the ISIMIP dataset https://data.isimip.org/search/tree/ISIMIP3a/InputData/climate/atmosphere/gswp3-w5e5/obsclim/.
Could you provide guidance on how net radiation is typically calculated? Thank you!

lwnet is calculated as the difference between incoming and outgoing long-wave radiation, where rlds from the ISIMIP dataset is incoming radiation and tas from the ISIMIP dataset is used as a proxy for outgoing radiation.

However, you can use rlds from the ISIMIP dataset without converting it into lwnet if you change the radiation setting in lpjml_config.cjson from "radiation" to "radiation_lwdown".
