Sub-parameters

P (average)

P (change)

P (anomalies)

Represented range

P (average): 0 mm/ 3,200 mm

P (change): -4.29mm/ 7.43 mm

P (anomalies): -113.75 mm/ 183.75 mm

Description

Average annual Precipitation considering monthly sums for the whole period (1979-2019). Monthly aggregates have been calculated based on the ERA5 hourly values of each parameter.

Annual change of the average total Precipitation for the whole period (1979-2019). The total change is the annual change multiplicated by the total number of years. A change of 2 millimeters per year represents a 80 mm total change between the start and the end of the period which is 1979-2019.

Annual Precipitation anomaly which is the average annual Precipitation for the whole period (1979-2019) comparing it to the average annual Precipitation of the year 2014-2019. The anomalies map shows the percentage deviation (per pixel) between 2014-2019 and the annual average for the whole region 1979-2019.

ERA5 Monthly aggregates Latest climate reanalysis produced by ECMWF / Copernicus Climate Change Service

Description

ERA5 is the fifth generation ECMWF atmospheric reanalysis of the global climate. Reanalysis combines model data with observations from across the world into a globally complete and consistent dataset.

Spatial resolution

The pixel size is 0.25 deg (approx. 28km at the equator)

Pixel size: 28 x 28 km (0.25 deg)

Temporal resolution

ERA5 data is available from 1979 to three months from real-time.

Monthly aggregates have been calculated based on the ERA5 hourly values of each parameter.
