EMD-WRF On-Demand and Custom-Area

Illustration of a EMD-Wrf Dataset in the windprospeting.com portal

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:

1. Time-Series - On-Demand - for 'virtual met-masts'
2. Spatial Areas - 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 accessible from the EMD-Youtube Channel:

• Webinar on Introduction to new EMD-WRF Mesocale Datasets

How to Order?

To get pointwise-timeseries data, you need meso-credits (one credit is worth one month of data). Credits can be ordered here:

• Time-Series: http://www.emd.dk/windpro/online-ordering/

To get meso-data for your own user-defined area, please select the area within the 'ordering' section of windPROSPECTING, then we will send you a quote:

• Spatial Data (along with time series): http://www.windprospecting.com/

Note: In order to access windPROSPECTING, use either windPRO (from the 'Data' drop-down-menu) or make a 'demo'-user. You are also very welcome to contact our sales department on email: sales@emd.dk.

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.
