European Reanalysis and Observations for Monitoring

• Reference historical databases:

1) in-situ observations (CRU, GPCC, ECA&D)

2) satellite CDRs (CM-SAF)

3) regional reanalysis of past weather (new!)

European Reanalysis and Observations for Monitoring

• Reference historical databases:

1) in-situ observations (CRU, GPCC, ECA&D)

long-term records but sparse

2) satellite CDRs (CM-SAF)

spatially extensive but short

3) regional reanalysis of past weather (new!)

complete but expensive and some bias
