  skos:definition """The World Water and Climate Atlas (WWCA)was developed jointly by
 the International Irrigation Management Institute (IIMI) and the
 Utah Climate Center at Utah State University. It aims at
 providing easily accessible climatic information necessary for
 the planning, design, operation, and management of water
 resources and irrigated agricultural systems.

 The atlas uses climatic data from over 56,000 stations
 world-wide with coverage from 1961 through 1990 and includes
 monthly and/or annual averages for evapo-transpiration, daily
 temperatures, precipitation, and the probability distributions
 of rainfall frequency and amount. The climatic factors are
 mapped at a 2.5 km resolution using state-of-the-art spatial
 interpolation techniques incorporating elevation modelling. The
 data sets contain best available data from international and
 local sources. The quality of the data varies, and has been
 partly improved by removing stations responsible for outlying
 values not explained by known effects. (Since there are many
 locations with sparse data, short periods of record, and
 spatially highly variable climate, it is still strongly
 recommended that the atlas be used together with local
 information.) Additional parameters included in the atlas are
 the moisture availability index that can be used to identify
 areas of rain-fed agricultura!  l potential and to evaluate
 needs for irrigation and drainage, and the net
 evapo-transpiration which is an indication of the required
 depth of irrigation.


 Use of the atlas:

 1. estimation of synthetic virgin stream-flow;
 2. evaluation of flow development potential;
 3. exploration of the impact of climate change on irrigated areas;
 4. salinisation studies.
