Introduction and Model Domain
This mesoscale wind resource map is available for public use. The map was developed in 2014-2015 by EMD International A/S, Denmark, and financed by the Environmental Support Programme (ESP3)/ Danida. The project was implemented for The Ministry of Energy and Mineral Resources, Indonesia, and ESP3. The applied mesoscale model is WRF (Weather and Research Forecast Model) with a spatial resolution of 0.029° (ca. 3 km) and driven by Era-Interim global data from the period 2004-2014.
The datasheet available can be found (here).
Dataset Parameters
A large quantity of useful parameters are available directly in WindPRO to aid in your analysis.
The different parameters in the EMD-WRF Indonesia dataset that are available from within WindPRO are shown in the table below.

Footnotes
- ↑ It is still being investigated whether this inverse Monin-Obukhov-Length can be used for stability clasification.
- ↑ 2.0 2.1 CloudWater and cloudIcing values are extracted directly from the WRF meso-scale model and are normal output parameters of the same run as the other parameters (wind, temperature etc.). They are controlled by the WRF microphysics scheme for which Ferrier was used. For further information, please access the numerous internet resources about WRF use. EMD has not done any validation on the parameters, so they are provided as is.
