Historical 500m daily Okanagan climate data

Description:

An inverse distance weighting (IDW) interpolation algorithm was used in conjunction with regional linear and non-linear regression to generate the climate surfaces from weather station data. In addition to latitudinal and elevation influences on temperature and precipitation, temperature inversions are accounted for using a two-layer method and lake effects are modelled by establishing the average long term temperature modification on station Tmax values [Neilsen et al. (2010)].
