UTCI-Test-Data

Independent data for testing the accuracy of approximations to values of the Universal Thermal Climate Index (UTCI) calculated by the UTCI-Fiala model, cf. Fig. 12 in https://doi.org/10.1007/s00484-011-0454-1 File name: UTCI-Test-Data.txt Purpose: Providing independent test data for assessing the accuracy of UTCI approximations This TAB-delimited file tabulates values of UTCI and the Offset (= UTCI - Ta) in °C calculated by the UTCI-Fiala model in comparison to UTCI approximated by the table look-up approach and the regression polynomial, respectively, for 1000 conditions with different input values of: Ta: air temperature in°C (range: -50 °C to +42 °C) Tr-Ta: difference between mean radiant temperature (Tr) and air temperature in °C (-17 °C to +50 °C) va: wind speed in m/s measured 10 m above ground level (1.0 m/s to 30 m/s) rH: relative humidity in % (5% to 100%) pa: water vapour pressure in kPa (0 kPa to 3.4 kPa) Calculated variables: Offset: Offset (= UTCI - Ta) in °C calculated by the UTCI-Fiala model (range -62 to 13 °C) UTCI: UTCI in °C calculated by the UTCI-Fiala model (range -111 to 43 °C) UTCI_Table: UTCI in °C approximated by the look-up approach using the data table ESM4 from the above referred publication UTCI_polynomial: UTCI in °C approximated by the polynomial regression function from ESM3 of the above referred publication Headers in line 34, first data row in line 35
