Introduction

This pages holds the list of parameters available for datasets originating from the EMD-WRF On-Demand Services - either as a time-series product or as a custom-area run from a user-defined area. You can find more information about the services at the following links:

There is also a webinar describing the content of the different EMD-Mesoscale Services, it is acessible from the EMD-Youtube Channel

Set of Standard Dataset Parameters

A large quantity of useful parameters are available directly in WindPRO to aid in your analysis. The different parameters in each On-Demand dataset is shown in the list below.

Required Modules/Licenses

To access the EMD-WRF Middle East mesoscale data the following licenses/modules are required in your WindPRO setup:

  • Basis
  • METEO
  • EMD-WRF Middle East

When the license fee is paid, you then have access to the full dataset without further cost. The price is available from the price-list on the EMD-homepage. Downloading of data is unrestricted for licenced users, however a "fair use" policy applies. Unlicenced users may download three months of data from any point, however, multiple downloads are not allowed from the same point.

Footnotes

  1. It is still being investigated whether this inverse Monin-Obukhov-Length can be used for stability clasification.
  2. 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.
