Daily runs based 00UTC and 12UTC data time are available for the following forecast times:

For data:

• medium range (10-day) HRES* & HRES*-WAM) Control10 and Control10-WAM analysis and forecasts based on 00UTC and 12UTC: hourly up to T+90, 3-hourly from T+93 to T+144, 6-hourly from T+150 to T+240.
• (medium range (15-day) ENS & ENS-WAM forecasts based on 00UTC and 12UTC: 3 hourly up to T+144, 6-hourly from T+150 to T+360.

For ecCharts:

• HRES*, HRES*-WAM ) analysis and forecasts based on 00UTC and 12UTC: 3 - hourly up to T+144, 6-hourly from T+150 to T+240 (day10).ENS, ENS-WAM forecasts based on 00UTC and 12UTC: 3 hourly up to T+144, 6-hourly from T+150 to T+360 (day15).. ???????

For Members of the Boundary Conditions (BC) optional programme (members using ECMWF IFS model forecast values as boundary conditions for their own local areas models) Medium Range forecasts based on 06UTC and 18UTC data times are available for the following forecast times:

• HRES*: medium range (10-day) HRES* & HRES*-WAM) Control10 and Control10-WAM analysis and forecast based on 06UTC and 18UTC:  hourly up to T+90, 3-hourly from T+93 to T+144

Note: Precipitation forecasts are provided as values accumulated from the start of the forecast integration.  The range of the daily variation of the forecast 2m temperature and wind gust is best estimated by retrieving the forecast maximum and minimum values.  The combination of accumulated and instantaneous forecast information can occasionally lead to inconsistencies as in both cases the valid time is defined as the time at the end of the period (e.g. during the passage of a cold front when significant precipitation amounts might be accumulated by theIFS the IFS models over the whole time interval though instantaneous cloud-free conditions will be shown at the end of the interval). ?????
