In the Climate Atlas of Croatia the 24 maps are published for the 1961-1990 period:

Mean annual air temperature Mean air temperature in January Mean air temperature in April Mean air temperature in July Mean air temperature in October Mean annual number of frost days (tmin < 0°C) Mean annual number of tropical nights (tmax ≥ 20°C) Mean annual number of warm days (tmax ≥ 25°C) Mean annual precipitation Mean precipitation in vevetation period Mean precipitation in Winter Mean precipitation in Spring Mean precipitation in Summer Mean precipitation in Autumn Mean annual number of days with Rd ≥ 1 mm Mean annual number of days with snow cover ≥ 1 cm Mean annual relative air humidity Mean annual global solar radiation Mean annual insolation Mean annual cloudiness Mean physiological equivalent air temperature in January Mean physiological equivalent air temperature in April Mean physiological equivalent air temperature in July Mean physiological equivalent air temperature in October

The regression kriging has been used as a mapping technique, based on the 1000 m resolution Digital Elevation Model as main predictor. Maps are available in a digital/raster format (ArcInfo asc) or as an image (bmp, tif). (Request form: DOC or PDF).
