Precipitation on extremely wet days (R99p)
Precipitation on extremely wet days (R99p): annual value of accumulated precipitation on “extremely wet days”, where an extremely wet day is defined as being greater than the 99th percentile of wet days (PPT ≥ 1,0 mm) during the reference period 1981-2010. The unit of measurement for R99p is millimeters (mm, equivalent to liters per square meter) and for AR99p (it is a relative anomaly) is percentage (%).
The evolution of R99p anomaly (AR99p, calculated as the quotient of the difference between the annual value of R99p and the mean value of R99p in the reference period 1981-2010 divided by this mean value of the reference period) during the period 1959-2020 is shown for the Pyrenees and for 4 areas of the Massif (Northern Pyrenees, Southern Pyrenees, Mediterranean Pyrenees and Atlantic Pyrenees); for each of the 26 series analyzed, the evolution of R99p index is shown.
The annual mean of R99p for the Pyrenees is obtained from the annual R99p values of 26 representative series of the Pyrenees massif (areas at different altitudes and on all slopes: north, south, east or Mediterranean and west or Atlantic), while the mean value of R99p for the 4 zones of the Massif is obtained from the annual R99p values of the representative series located in each zone.

Evolution of the annual R99p anomaly (AR99p, in %) in the Pyrenees for the period 1959-2020. Green points (positive AR99p) indicate a R99p value higher than the reference period value and orange points (negative AR99p) indicate a R99p value lower than the reference period value.
The dotted line shows the linear trend of the series (-1,8 %/decade).

Bulletin of Climate Change Indicators of the Pyrenees 2020
The Bulletin of Climate Change Indicators of the Pyrenees (BICCPIR) 2020 aims to deepen the knowledge of the anthropic climate change effects in the Pyrenees. Thus, information on the climate evolution is provided through a set of indicators grouped by systems.
