MED-GOLD Indicators for the Wine pilot service over Iberian Peninsula from ERA5 Reanalysis 1979-2020

Indicators of interest for the Wine sector over the Iberian Peninsula using ERA5 Reanalysis data  for the period 1979 to 2020:

1. Growing Season Temperature (GST)  [Temp averaged between April and October]
2. Spring Rain (SprR) [ Precip cumulated between 21 apr and 21 Jun],
3. Harvest Rain  (HarvestR) [ Precip cumulated between 21 aug and 21 Oct]
4.  (SU35) -number of days with temperature higher than 35°C [for April ot October],
5. Warm Spell Duration Index (WSDI) [days with at least 6 consecutive days when the daily temperature maximum exceeds its 90th percentile for April to Oct]

Wine risk indicators, implemented specifically for the MED-GOLD Wine pilot service by ENEA and SOGRAPE VINHOS S.A.:

1. Sanitary Risk Index= offgts*offsp*(percentile(SprR))+offhart*percentile(HarvestR)+(100-percentile(GST); with offhart=1.; offsp=1;  offgts=1.; if percentile (SprR)>= 60; offsp=1.5;   if percentile (GST)<= 40; offhart=1.5; if percentile (GST)>=70;  offgts=1.5; where the percentile are here computed starting from the distribution over the 1993-2106 hindcast period to be consistent and comparable with the seasonal forecast
2. Heat Risk Index = percentile(GST)+percentile(SU35_AMJJASO) + percentile(WSDI_AMJJASO),where the percentile are here computed srarting from the distribution over the 1993-2106 hindcast period to be consistent and comparable with the seasonal forecast
