Monthly means of ambient temperature

This resource interpolates monthly means of ambient temperature for the whole globe.

Resource information

The resource serves monthly values of ambient temperature for the whole world. Monthly values are taken from the climatological database METEONORM (Remund and Kunz, 1999), which is based on WMO CLINO 1961-90 (1998). It contains 2500 stations.

Input variables:

1. Longitude and latitude in degrees and decimals of degrees. Western longitudes and northern latitudes are positive.

2. Altitude above sea level in meter. If ommitted, the mean altitude of the 5' grid is taken.

Source

Hourly values of ambient temperature is interpolated according SODA interpolation task. The data of the meteorological stations are interpolated on-line.

Accuracy:
The interpolation has an rmse of about 2°C for monthly values.
