Update on  03-11-2017:

Our 'ssrd' field is actually correct. The issue described last month only concerns our seasonal forecast system, but not our S2S system.

1. Brief  description:

All ssrd data is affected  (values are much too high; it comes from a post-processing issue where the direct downward solar radiation has been mistakenly added to the total (i.e. direct + diffuse) downward solar radiation). The issue will be neither fixed in the past re-forecasts nor in the past forecasts as it would require excessive work. It has not been fixed in new forecasts either in order to avoid inconsistencies with the re-forecast and previous forecasts.

2. Recommendation:

Not to use ssrd data at all until the next Meteo-France forecast system update (estimated in 2019).
Higher resolution of sea ice cover and sea surface temperature (not error just a technical exception)
Info

1. Brief  description:

Two surface  parameters (sea ice cover and sea surface temperature) after the model upgrade to the version CNRM-CM6.1 have higher resolution (1x1)  than the other surface parameters (1.5x1.5) in both real-time (since 2020-10-22) and reforecast (model version date 2019-07-01) outputs. That higher resolution is the same as the one agreed for the newly added 9 ocean parameters. 

2. Recommendation:

If needed, users can retrieve those parameters with the same resolution as other surface parameters (1.5/1.5 degree regular lat-lon grid) by specifying it explicitly in their Web-API requests.

BoM (ammc)

Wrong maximum values of surface air maximum temperature (Tmax) at some points for BoM  data
