RESULTS - OZONE CLIMATOLOGY

COST 726 OZONE CLIMATOLOGY over Europe
( 25E to 35W and 30N to 80N )
from 1950 to 2008
 

Description:
The COST 726 Total Ozone Climtology (COC) consists of three data files and a easy to use program to extract a time series for a certain location.
The files you have to download are listed below.
The size of the data files is 52 Mb + 31 Mb + 4 Mb. Unzipped files will need 430 Mb of disk space
Put all files in the same directory.
The program only needs latitude and longitude (decimal point) divided by a comma as input (e.g. 52.21,15.33) and "enter".
It may need a few minutes to receive the result.
Time series, daily means for the period 01.01.1950 -20.03.2009 is stored in a simple ASCII-file as "timeseries.txt" in the same directory.
Please not that this file is overwritten each time you run the program. So do not forget to rename the file!.
The JGR paper(22MB!!) describing the method used in the COC preparation could be also downloaded.
