Introduction
"Heliosat Solar" is a satelite based surface radiation dataset produced and delivered by CM SAF (Satellite Application Facility on Climate Monitoring). The windPRO dataset is composed of two different datasets, namely:
- Surface Radiation Data Set - Heliosat (SARAH) - Edition 2.1 : This dataset covers the period from 1999-01-01 to 2017-12-31
- ICDR SEVIRI Radiation - based on SARAH-2 methods : This dataset is an operational dataset that covers the period from 2018-01-01 to present
The Validation report of the ICDR dataset concludes that there is a resonable consistency between the two datasets.
Dataset Overview
- Content:: Surface radition parameters to be used in Solar calculations in windPRO
- Spatial Resolution: The dataset is available on a regular geographical (lat/lon) grid at 0.05x0.05 resolution (around 5 km).
- Temporal Resolution: 30 minute values.
- Coverage: The dataset has an extend +- 65 degrees in both latetidues and longitudes. In windPRO, offshore coverage is at a distance of approximately 300 km from any known coastlines.
- Period: 20+ years. The EMD databases will hold data back to 1999.
Data Parameters
The windPRO dataset only contains parameters needed for solar calculations. The parameters are listed below.
| Parameter | Unit | Description |
|---|---|---|
| time | UTC time stamp (half hourly) | |
| SIS | w/m2 | Surface Incoming Shortwave Irradiance |
| SID | w/m2 | Surface Irradiance Direct |
All parameters are instantaneous. The two parameters SIS and SID can be used to calculate the diffuse radiation as SIS-SID = diffuse radiation.
Required Modules/Licenses
To access the Heliosat Solar data from within windPRO - the following licenses/modules are required in your windPRO setup:
- BASIS
- METEO
- SOLAR
When the license fee is paid, you then have access to the full dataset without further cost. Downloading of data is unrestricted for licenced users with an active service subscription, however, a "fair use" policy applies. Visit EMD online ordering to purchase the necessary licences.
Attribution
If data from this dataset is used within any private or public disseminations, then EMD and its data providers must be acknowledged.
