Definition:HadEX2 is a global land-based climate extremes dataset derived from RClimDex using high quality daily data from about 7400 temperature stations and 11600 precipitation stations. The dataset consists of 27 indices of temperature and precipitation on a 2.5° x 3.75° grid from 1901 to 2010, representing annual and monthly values derived from daily station data.
Available indices are: Max Tmax (TXx), Max Tmin (TNx), Min Tmax (TXn), Min Tmin (TNn), Cool nights (TN10p), Cool days (TX10p), Warm nights (TN90p), Warm days (TX90p), Diurnal temperature range (DTR), Max 1-day percipitation amount (Rx1day), Max 5-day percipitation amount (Rx5day).
