Abstract:
This experiment contains forecasts from the LMK (COSMO-DE) high resolution model of DWD (2.8km horizontal resoultion and 50 model levels). Model runs are started every 3h at 00, 03, 06, 09, 12, 15, 18 and 21 UTC with a forecast range of +18h. LMK (COSMO-DE) is an operational forecast model of DWD. Therefore, we adapted the output of the model as close as possible to the tigge+ list, but there are some differences; see dataset summaries.
For a detailed description of the LMK (COSMO-DE) model, please contact the originator of the data.
All datasets for COPS in the database have an output frequency of 15 minutes. If the variables are not provided by LMK (COSMO-DE) with an output frequency of 15 minutes then the hourly output has been linearily interpolated in time.
LMK (COSMO-DE) provides only a subset of the TIGGE+ variables with an output frequency of 15 minutes. These are:
Total precipitation (all types) (kg/m**2) acc_st 011 002 TPT2
Precipitation: grid-scale only, rain (kg/m**2) acc_st 102 201 SURF
Precipitation: grid-scale only, snow (kg/m**2) acc_st 079 002 SURF
Precipitation: grid-scale only, graupel (kg/m**2) acc_st 132 201 SURF
Precipitation rate: grid-scale only, rain (kg/s/m**2) inst 100 201 SURF
Precipitation rate: grid-scale only, snow (kg/s/m**2) inst 100 201 SURF
