      <gmd:abstract>
        <gco:CharacterString>The UK Universities Global Atmospheric Modelling Programme (UGAMP) ozone climatology project. This  dataset contains a 3-dimensional climatology of ozone monthly means, combining various satellite observations and ozone sonde data. The data are global and covers 1987.

Each file contains a ligne of text followed by the variable itself, in free format.

Every single three-dimensional field var is stored as

(((var(i, j, k), i=1, 144), j=1, 73), k=1, 47)
where
i is the longitude index (from 0°E to 357.5°E by 2.5°);
j is the latitude index (from South Pole to North Pole by 2.5°);
k is the level index (from top to bottom).

Every two-dimensional field (zonal means) is stored as

((var(j, k), j=1, 73), k=1, 47)
with the same conventions as above.</gco:CharacterString>
