ALZATE VELASQUEZ, Diego Fernando et al. Regnie interpolation for rain and temperature in the andean, caribbean and pacific regions of Colombia. Colomb. for. [online]. 2018, vol.21, n.1, pp.102-118. ISSN 0120-0739.  https://doi.org/10.14483/2256201x.11601.

A regionalized rain interpolation model: Regionalisierte Niederschlage (REGNIE) was implemented to interpolate rain and average air temperature for the Andean, Caribbean and Pacific Regions in Colombia. This model integrated terrain slope and aspect obtained from the digital elevation model and the climatological average of 1440 precipitation time series and 259 temperature time series registered in the same number of weather stations for each variable. Multiple linear regression models of annual rainfall and annual average air temperature were obtained according to the model and geoprocessing tools were used for the generation of interpolated surfaces. Statistical results of REGNIE surfaces were similar to those obtained with SPLINE and IDW methods for precipitation (determination coefficient of 0.81 and 55.6 mm mean error) and better for average mean temperature (coefficient of determination 0.99 and average error of 0.02 °C).
