Things TODO/read/learn... @ Jan 2019

• @ECMWF test dataset available for #WRF users - ECMWF has set up a public FTP that contains a test dataset of the parameters required to run the US Weather Research and Forecasting model (WRF). https://confluence.ecmwf.int/display/UDOC/ECMWF+WRF+Test+Data
• have a look to the following links all related to a tool to read grib files stored in the CDS

• 1 May - 31 Aug Coding phase
• 20 Sep Workshop
• List of challenges 
• Challenge #12: Machine learning for predicting extreme weather  hazards
• Previous edition
• Workshop
• Newsletter
• ECMWF Winter Newsletter no 158 (further reading needed)
  
•  Meteorological analysis of 29 Oct 2018 in Italy (Magnusson)
• ERA5 now back to 1979 available @ CDS (back to 1950 by the end of 2019)
• Predictability of NAO
• A new Nature Run produced by ECMWF:
• 14-month long, starting 30 Sept 2015 at 00 UTC
• model cycle 43r1, res @ 9 km, 137 vertical levels, output 3 hours
• 1 month of data --> 4 TB
• download at https://www.cira.colostate.edu/imagery-data/ecmwf-nature-run/
• Cold spells in Europe: good forecast up tp 2.5 weeks in advance (Ferranti et al, 2018 How far in advance can we predict changes in large-scale flow leading to severe cold conditions over Europe?
  QJRMS)
• Model and DA improvements:
• Continuous DA uses observations only 30-minute old (instead of 2 hours). Improvement in the next model cycle by the end of 2019
• 50-member EDA which has the same computational cost of the current 25-member EDA (introduced in 2013, the 10-member EDA was firstly introduced in 2010). Improvement in the next model cycle by the end of 2019. Does it determine the end of SVs?
• Improvements on the non-hydrostatic core of the IFS model by using the FVM (Finite-Volume Module), which reduces the parallel communications
• CAMS reanalysis
• from 2003 to near real time
• providing aerosol concentrations such as O3, CO, NO2
• model cycle 43r1
• resolution about 80 km
