360-day to Gregorian calendar climate model output conversion
Published: 2023-07-05
Subjects: Climate, Earth Sciences, Meteorology, Physical Sciences and Mathematics
Data from some climate model simulations is in a 360 days per year format, that is, every month is 30 days long. The main reason for this is analytical convenience in creating seasonal, annual and multi-annual means which are an integral part of climate model development and evaluation. This work illustrates a method to convert daily-mean, 360-day calendar climate model data into 'real', [...]
