The Climate Moisture Index (CMI) was calculated as the difference between annual precipitation and potential evapotranspiration (PET) – the potential loss of water vapour from a landscape covered by vegetation. Positive CMI values indicate wet or moist conditions and show that precipitation is sufficient to sustain a closed-canopy forest. Negative CMI values indicate dry conditions that, at best, can support discontinuous parkland-type forests. The CMI is well suited to evaluating moisture conditions in dry regions such as the Prairie Provinces and has been used for other ecological studies. Mean annual potential evapotranspiration (PET) was estimated for 30-year periods using the modified Penman-Monteith formulation of Hogg (1997), based on monthly 10-km gridded temperature data. Data shown on maps are 30-year averages. Historical values of CMI (1981-2010) were created by averaging annual CMI calculated from interpolated monthly temperature and precipitation data produced from climate station records. Future values of CMI were projected from downscaled monthly values of temperature and precipitation simulated using the Canadian Earth System Model version 2 (CanESM2) for multiple RCP radiative forcing scenarios. Multiple layers are provided: Climate moisture indexes are shown across Canada for a reference period from 1981-2010. Future projections using RCP 8.5 are given for three different time periods: 2011-2040; 2041-2070; 2071-2100. Future projection using RCP 2.6 given for time period: 2071-2100 Gouvernement du Canada; Ressources naturelles Canada 1 (800) 661 2638 NRCan.fgp-pgf.RNCan@Canada.ca Drought,climate,humidity,warming,climate,emissions,atmospheric,pollution Arctic Rating Availability for the week: 0.979 Availability for year 2021: 0.984 Spatineo Rating OGC:WMS 1.3.0 -122.9152867999896 -9.960887739198247 36.207944260982444 62.41801206232004 Licence du gouvernement ouvert - Canada (http://ouvert.canada.ca/fr/licence-du-gouvernement-ouvert-canada) ASDD nodes zserver z3950://www.google.com:6668/geonetwork z3950 ASDD Z3950 zserver http://webservices.maps.canada.ca/arcgis/services/NRCan/climate_moisture_index_en/MapServer/WmsServer?SERVICE=WMS&REQUEST=GetCapabilities http://directory.spatineo.com/service/69036 WWW:LINK-1.0-http--link Service in Spatineo Directory
