Contents of CD-ROM

The CD-ROM contains 25 fixed ASCII format data files named <element number>.dat, two fixed ASCII format files 
station.dat and normal.dat, and the ASCII text format file readme.txt. Data from the CD-ROM may only be used 
with proper reference to the accompanying report (Laursen, Ellen Vaarby, Rikke Sjlin Thomsen and John 
Cappelen, 1999. Observed Air Temperature, Humidity, Pressure, Cloud Cover and Weather in Denmark - 
with Climatological Standard Normals, 1961-1990. DMI Technical Report No. 99-5).

Station file: station.dat
The station catalogue contained in the file station.dat describes the station no., element
no., name, position, elevation and first and last year of the climate element series in this report. Each record 
in the file contains information about one station/element. The file is sorted by station
no. /element no. and has the following layout:

Position	Format	Description

1-8 	F8.0 	Station no.
9-16 	F8.0 	Element no.
17-36 	A20 	Station name
37-38 	F2.0 	Latitude (degrees)
39-40	F2.0	Latitude (minutes)
41-41	A1	Northern (N) or Southern (S) hemisphere
42-44	F3.0	Longitude (degrees)
45-46	F2.0	Longitude (minutes)
47-47	A1	East (E) or West (W) of Greenwich
48-51 	F4.0 	Elevation (metres above mean sea level)
52-55	F4.0	First year in the data series
56-59	F4.0	Last year in the data series



Normal files: normal.dat

Normal values for the standard normal period 1961-1990 and other periods are contained in
the file normal.dat. The file contains normal values for all stations described in the station
catalogue. The file is sorted by station no. /element no.
Each record in the file contains the mean monthly and annual values - all in units of 0.1 - from
one station/element no. in the following format:

Position	Format	Description
1-6 	F6.0 	Station no.
7-12 	F6.0 	Element no.
13-18 	F6.0 	First year in normal period
19-24 	F6.0 	Last year in normal period
25-30 	F6.0 	January normal value
31-36 	F6.0 	February normal value
37-42 	F6.0 	March normal value
43-48 	F6.0 	April normal value
49-54 	F6.0 	May normal value
55-60 	F6.0 	June normal value
61-66 	F6.0 	July normal value
67-72 	F6.0 	August normal value
73-78 	F6.0 	September normal value
79-84 	F6.0 	October normal value
85-90 	F6.0 	November normal value
91-96 	F6.0 	December normal value
97-102 	F6.0 	Annual normal value


Monthly files: <element number>.dat

Time series for all the stations presented in this report are contained in the files <element
number>.dat. The files are sorted by station no. /element no., year and month
(month 13 gives the annual total). Each record in the files contains one monthly or annual
value for one station/element no. in the following format. The units of the values can be
seen in the table in Appendix 1. Please also note that the 'Date' variable only exists in the
files concerned with extreme values (format is [month][day] i.e. 825 for 25 August):

Position 	Format 	Description
1-6 	F6.0 	Station no.
7-12 	F6.0 	Element no.
13-18 	F6.0 	Year
19-24 	F6.0 	Month (1-12 and 13 for annual)
25-30 	F6.0 	Value
31-36 	F6.0 	Date.
