#601Full missing month in CAMS Radiation Service when no cloud data were available

Since 2018-06-20, CAMS Radiation Service notifies gaps in Apollo cloud data by:

  • large gaps (1 full day or more) are not filled and are notified with irradiation=NaN
  • gaps smaller than 1 day are filled and are notified with reliability=0

A side effect was that monthly irradiation are equal to NaN as soon as one day of Apollo data was missing.

As our users indicated that this behavior was not user-friendly, we restored the gap filling for monthly requests.

It can be unspecified. Up to now, in such case CAMS Radiation Service returned 0. Now, "unspecified value" is -1.

So possible values for cloud coverage are :

  • [0; 100] : for valid value.

#601CAMS Radiation Service when no cloud data are available

So far, CAMS Radiation Service sometimes notified a gap with irradiation=NaN and sometimes with reliability=0.

This new version is more coherent:

  • large gaps (1 full day or more) are not filled and are notified with irradiation=NaN
  • gaps smaller than 1 day are filled and are notified with reliability=0
The new version of CAMS Radiation Service notifies large gaps (1 full day or more) with irradiation=NaN
