The increments shown are only a guide and do not imply that they occur in every case. 

Users should assess the modify forecasts in the area of interest after assessment the IFS analysis of temperature and moisture against observations in the area of interest and modify forecasts accordingly:

• temperature and dew points against observations.
• soil moisture and whether any increase is due to forecasts or observed rain, or perhaps due to model soil moisture increments.

ECMWF is currently investigating problems with soil moisture increments.

Summary of soil temperature errors:

Soil moisture and temperature is modelled in four soil levels but there is a considerable lack of real-time observations of soil condition and moisture content.  Nevertheless heat and moisture fluxes have an impact on model surface and 2m temperature and moisture.
