A Methodfor Daily Temperature Data Interpolationand Quality Control Basedonthe Selected Past Events
Presentation for the 6th Seminar for Homogenization and Quality Control in Climatological Databases
Budapest, May 2008
Climatological stations in the complex terrain of northwestern Slovenia, 1980: mountain-, plateau-, slope-, valley/basin-stations
An example of strong horizontal temperature (Tmax, yellow) gradient due to daily precipitation gradient (blue), August 29, 2003 (Val Canale flood). Stations below 1000 m are marked by a red circle.
Temperature time series on Rudno polje (Pokljuka) 18-19 July, 2007 (T0) and arbitrary similar series (T1, T2)
An example of temp. estimatations at the reference stations, the final result and the measured value (in brackets)
Standard deviation of the error in °C (Bilje + monthly correct. 1.80, Postojna + monthly correct. 2.35)
Topography in western Slovenia with marked station locations
T21 (the day before), T7, Tmin, T14, Tmax
Standard deviation depending on the value of kdev
Standard deviation of the error series
Result comparison, March 2004
the reason for a large part of the variance remained unexplained (other meteorological variables and data at the target station should be included)
