Arjun Adhikari and Andrew J. Hansen, 2018, Historical Thornthwaite Moisture Index (MI) under IPSL-CM5A-MR GCM across North Central U.S. (1980-2005): Montana State University.


Historical and projected climate data and water balance data under three GCMs (CNRM-CM5, CCSM4, and IPSL-CM5A-MR) from 1980 to 2099 was used to assess projected climate change impacts in North Central U.S. We obtained required data from MACA data ( Historical time period ranges from 1980 to 2005, and projected time period ranges from 2071 to 2099. The climate data includes temperature and precipitation whereas water balance data includes Potential Evapotranspiration (PET) and Moisture Index (MI) estimated using Penman-Monteith and Thornthwaite methods defining as Penman PET, Penman MI, Thornthwaite PET and Thornthwaite MI. Both types of MI was estimated as a ratio of Precipitation and [...]

This data was estimated from historical Precipitation and PET estimated using Thornthwaite equation and existing precipitation data available in MACA data to compare with MI estimated through Precipitation and Penman-Monteith PET.
