Abstract:
Users are recommended to consult the author (malcolm.mistry@unive.it / malmistry1977@gmail.com) for an updated version which includes more recent years.
The human discomfort indices (HDIs) are computed using meteorological parameters from the Global Land Data Acquisation System (GLDAS) ver. 2 (@ 0.25 degree global gridded resolution). The dataset referred to as "HDI_0p25_1970_2018" covers 49 years over the period 1970-2018. Following HDIs are included:
(i) Apparent Temperature (AT) indoors: Deg Celsius
(ii) AT outdoors in shade, as defined by Australian Bureau of Meteorology (ABM) and National Oceanic and Atmospheric Administration (NOAA): Deg Celsius
(iii) Discomfort Index (DI): Unitless
(iv) Humidex (HDEX): Unitless
(v) Heat Index (HI): Deg Celsius
(vi) Wet Bulb Globe Temperature (WBGT), as defined by ABM and by Gagge and Nishi (1976): Unitless
(vii) Wet Bulb Temperature (WBT): Deg Celsius
(viii) Windchill Temperature (WCT): Deg Celsius
HDIs on daily timesteps covering years 1970-2018 are available as individual (annual) NetCDF-4 (.nc4) files. The files follow the naming convention 'gldas_HDI_daily_year.nc4'; wherein "HDI" is the abbreviation of the index (AT_indoors, AT_outdoor_shade_ABM, AT_out_shade_NOAA, DI, humidex, HI, wbgt_ABM, wbgt, wet_bulb or windchill_T), and "year" the time period over which the HDI are computed on daily timesteps. Some of the indices use two methodologies for computation as defined in literature (e.g. ABM, NOAA). These abbreviations are also included in the filenames and the details (units, attributes etc) can be checked using 'ncdump -h filename.nc4'.
In addition to individual HDI, the associated meteorological variables (referred to 'secondary variables') used to compile the HDIs are available upon request from the author. These variables (all on daily timesteps for the same period 1970-2018) include vapor pressure (vp), saturation vapor pressure (svp), vapor pressure deficit (vpd), relative humidity (rh). 'vpd' is actually not used in the computation of any of the HDI, but generated as an add-on variable using 'rh' and 'svp'.
Grid-cells with missing values are identified by "1.e+20f".
Important: GLDAS ver-2 comprises of two sub-versions (ver. 2.0 for period 1970-2010 and ver 2.1 for period 2000-present day). The HDIs computed using the input variables may show a break in time-series at a few locations around the years 2010-11. Users are therefore advised caution when using the data for trend analysis for instance. Further details on the merging of the two versions can be found below:
