If I understand correctly , Global-hourly Integrated Surface Datasets (Global Hourly - Integrated Surface Database (ISD) | National Centers for Environmental Information (NCEI)) has retired, and superceded by Global Historical Climatology Netowrk hourly (GHCNh) Global Historical Climatology Network hourly (GHCNh) | National Centers for Environmental Information (NCEI) . I am wondering if people has adapted to this change. I am using Calpuff instead of Aermod, but information for Aermod is always helpful to me.
Thanks,
