- Abstract
- Actual Evapotrans is a point theme representing the sum of evaporation and plant transpiration to the atmosphere from throughout the world. Measurements are represented by points at every.5 degrees and provided for every month of the year. This dataset is a part of the Global Climate Database from the Global Change Department National Institute of Public Health and Environmental Protection.
- Purpose
- For educational, non-commercial purposes only.
- Supplemental Information
- The evapotranspiration scheme used is developed by Prentice et al. It reference is: Prentice, I.C., Sykes, M. Cramer, W., 1993. A simulation model for the transient effects of climate change on forest landscapes. Ecological Modeling, 65: 51-70.

- Data Quality Information
- Attribute Accuracy Report
- The quality has been improved by using stringent station selection criteria for the climatic normal period 1931-1960. The database is now based on c. high-quality 16000-20000 stations world wide. The interpolation methodology has been improved by using a empirical correction scheme with locally derived lapse rates. This scheme works well for both temperature and precipitation.
