Meteorological Data

 

Information

Observations from 113 meteorological stations spread over an area from about 49 to 62°N and 84 to 115°E are available. The data span the time periods from September 15 to October 31, 1997 and from May 1 to August 15, 1998. The nominal time step of the records is 3 hours, but depending on the variable or station other time steps (6, 12, 24 hours) occur. Also, in many instances, the series are incomplete.

The meteorological data base contains the following variables: pressure, windspeed, temperature, dew point, weather, cloudiness, precipitation and others. A more detailed description of the meteorological data is available in German.

Temperature and Precipitation Plots

Temperature and precipitation series

For easy checking of the meteorological conditions during ERS SAR acquisitions, plots of temperature and rainfall (like in the figure above) were produced. The vertical lines in the plots represent the exact dates and times of the ERS SAR data takes. The text beside these lines indicate the satellite (ERS-1 or ERS-2), the orbit number, and the acquisition date. Plots from all stations in the area of interest can be displayed by clicking on the WMO number in the table below. The first two rows of the table contain the track and frame numbers of the ERS SAR scenes that are within a distance of 50 km from the meteorological stations.
