Info

1. Brief  description:

All S2S parameters were affected in that period. The corrected data was re-archived on June 17 2016.

The problem on the provider's side was caused by a bug in the last versions of EMOS and MARS (issued in March) that was avoided by using the previous version of MARS.

2. Recommendation:

If lfpw data from the given period was downloaded in the period 19.5.2016-17.6.2016. it should be deleted and the correct version of the data downloaded again.
Wrong 10-meter wind fields
Info

1. Brief  description:

10-meter wind fields (zonal and meridian) are effectively wrong.

2. Recommendation:

Not to use 10-meter wind  data at all until the next Meteo-France forecast system update (estimated in 2019).
Wrong surface solar radiation downwards (ssrd)  data
Info

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).
