EMD-WRF On-Demand and Custom-Area

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:

• Time-Series - On-Demand - for 'virtual met-masts'
• Area - On-Demand - for time-series within a larger domain and spatial climatic data

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

• Webinar on Introduction to new EMD-WRF Mesocale Datasets

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.
