Statistics on Access to the HelioClim Databases
|
This graph exhibits the number of requests, in thousands, made to the HelioClim databases per year. Data for current year result from projection. HC1, HC2, HC3 means respectively HelioClim-1, -2 and -3. In 2008, the use of HC-3 was recommended in place of HC-2. A request may deal with a single geographical point or an area, a single instant or a large time period. Prior to 2006, the amount of data for one request was limited to 1 year for daily values and 1 month for hourly values; this explains the fall in request number in 2006 compared to previous years for HC-1. |
