HC3 data available at 11:30 PM UT
The Meteosat Second Generation images, provided by Eumetsat, are acquired every 15 minute. They are processed using the HelioSat-2 method every night at 9:00 PM UT to update the HelioClim-3 database. This process takes approximately 2h-2h30. The data are though available around 11:30 PM UT.
The Eumetsat agreement stipulates that we can provide to our Customers the Meteosat-derived products with a minimum delay or 24 hours without additional fee. In order to be allowed to provide the irradiation values as soon as they are avaible on our server, we had to purchase an additional annual fee, that we must partly pass on our annual subscription prices, if the Customer makes the request for the "near real time" option. Please contact us if you need a quotation for this service.
First steps to real time: MICROMATA
One of our Customers, named MICROMATA, formulate a particular request: for the global monitoring of the PV installation in Germany, they needed the immediate delivery of maps of irradiation over Germany, i.e. as soon as they were processed after Meteosat image acquisition. This particular field of the monitoring was named the nowcasting.
In May 2011, the objective was achieved, and irradiation maps over Germany were sent approximately 3 minute after image reception. As described in Fig.1, They compute the global productible of the country using our maps in conjunction with a series of other information:
- The electrical production actually measured at a large number of geographical locations
- the current and continuous temperature field over the country
- The classification of the different PV installation types accross the country
The result of such service is available here.
