ISLSCP II CRU05 Climate Time Series (1986-1995) for Global Land Areas

File Name Convention
################################################################################
There are 13 data files in this data set which includes 12 compressed 
(*.zip files)  and 1 changemap file.

The data files are named using the following convention:

cru5_variable_Xdeg.zip 
    where: cru5 - identifies these data as CRU version 5.
    variable - is the climate variable name, one of the following six 
               variables: cloud_covr, diurnal_tmp, precip, temp_mean 
               vapor_pres, wetday_frq.  
    Xdeg - is 1deg for 1.0 degree, or hdeg, for 0.5 degree spatial resolution 
         in both latitude and longitude. 

The 0.5 degree data files (hdeg) also contain differences files (*.dif), which 
have the points in the original 0.5 degree files that did not match the ISLSCP
Initiative II Land/Water mask.

The 13 data files within this data set are for the time peroid January 1986 
(198601) through December 1995 (199512). The 1 degree (1d) files, contain
120 *.asc files when extrapolated, while the one-half degree (hdeg) files
contain 240 files (120 *.asc and 120 *.dif). The 12 *.zip files and the 1
*.asc file are named as follows:

 1. cru5_cloud_covr_1d.zip
 2. cru5_cloud_covr_hdeg.zip
 3. cru5_diurnal_tmp_1deg.zip
 4. cru5_diurnal_tmp_hdeg.zip
 5. cru5_precip_1deg.zip
 6. cru5_precip_hdeg.zip
 7. cru5_temp_mean_1deg.zip
 8. cru5_temp_mean_hdeg.zip
 9. cru5_vapor_pres_1deg.zip
10. cru5_vapor_pres_hdeg.zip
11. cru5_wetday_frq_1deg.zip
12. cru5_wetday_frq_hdeg.zip
13. cru5_climate_hd_changemap.asc

ASCII Data Format
-----------------
All of the files in the ISLSCP Initiative II data collection are in the ASCII 
gird, or text format. The file format consists of numerical fields of varying
length, which are delimited by a single space and arranged in columns and rows.
The half-degree files have 720 columns by 360 rows. The 1.0 degree files have 
360 columns by 180 rows. 

These files are all gridded to a common equal-angle lat/long grid, where the 
coordinates of the upper left corner of the files are located at 180 degrees W,
90 degrees N and the lower right corner coordinates are located at 180 degrees
E, 90 degrees S. Data in the files are ordered from North to South and from 
West to East beginning at 180 degrees West and 90 degrees North.
