Abstract

When calculating climatological variables in regular grids geostatistical methods prove to be very powerful. However, operationally we are faced by many challenges as the consequence of imperfect reality. The basic input in spatialisation procedure are measurements with their measurement error. The spatial density of point measurements is never adequate for our demands and is homogenous neither in space nor in time. The use of auxiliary variables with higher spatial density to resolve the spatial variability of the treated variable can help, but again, the coverage of measurements regarding the auxiliary data domain should be high enough. Another issue regarding measurements is their representativity, which could be inadequate for the task we have to solve. Inclusion of modern, remote sensing measurements with relatively good spatial coverage in spatialisation process is often advantageous but poses another challenge, how to ensure temporal homogeneity of calculated grids. Finally, there are user demands, which are reasonable, but sometimes from the above described or some additional reasons unsolvable for data providers.
