Die #Klimakrise trifft die #Welt:
Der August 2025 war weltweit der drittwärmste seit Beginn der Aufzeichnungen.
Laut #Copernicus-#Klimadaten lag die globale Durchschnittstemperatur bei 16,60 °C und damit 0,49 °C über dem Schnitt von 1991–2020. Im Vergleich zum vorindustriellen Niveau beträgt der Anstieg 1,29 °C.
Besonders #Europa erlebte zwischen dem 8. und 18. August eine ausgeprägte #Hitzewelle mit deutlichen Temperaturabweichungen.
I've been following the news about discontinuing #NOAA data with sadness and apprehension. This is all very messed up.
Currently I rely heavily on #nasapower #gpm and #chirps data for monitoring agroclimatic risks. So I have two questions:
1) How are those data affected by those NOAA cuts?
2) Even if the data is not affected, I'm considering substituting those sources. What are some candidates? For NasaPower, #era5 looks like a good candidate. What about precipitation? Any jaxa products?
Paper alert🌧 Working in a region without high-resolution #precipitation data, and #reanalysis products show low performance? We used a rainfall generator and estimated the parameters from #ERA5-Land & #COSMO-REA6 data! #ProudSupervisor #hydrology #water

Der Mai 2025 war global der zweitwärmste Mai seit Beginn der Aufzeichnungen.
Laut ERA5-Daten lag die durchschnittliche #Oberflächentemperatur 0,53 °C über dem Mittel von 1991–2020 und 1,40 °C über dem vorindustriellen Niveau.
Nur der Mai 2024 war wärmer. In den letzten 23 Monaten überschritt die globale Temperatur 14-mal deutlich die 1,5-Grad-Marke.

Since July 2023, 21 of the last 22 months have seen global average temperatures 1.5ºC above the pre-industrial level, according to #ERA5 data - with July 2024 just 0.02°C below that mark.

Anyone out there got any tips on converting ERA5 .grib files? Trying to get a load of data for a project at work and running up against the CDSAPI computation limits for netcdf files (unless I want to split files daily massively increasing the number of total requests). Running up against error after error with xarray, earthkit and cfgrib when trying to convert. Would love some help.
Out now! Available in the #C3S data store: ERA5 hourly time-series data on single levels from 1940 to present. As a regridded subset of the full #ERA5 dataset on native resolution, it is designed for retrieving long time-series for a single point.

The C3S global temperature trend monitor, based on #ERA5, allows you to explore how the estimate of the time to 1.5°C global warming has changed in recent years. While it should not be interpreted as a forecast, it does show trends in global warming.
Time series - near-surface air temperature
This chart shows daily averages of global mean near-surface air temperature anomalies from the #ERA5 global reanalysis dataset, from January1940 up to two days behind real-time.
Reanalysis datasets like #ERA5 combine conventional weather observations and data from satellites with a computer model of the Earth system. But what does that mean in detail and what is the degree of uncertainty of ERA5 temperature data?

Predicting climate trends, guiding policies, and protecting communities: #ERA5 is a foundation for informed decision-making and action.

📣 We are pleased to announce that the much awaited #ERA5 and ERA5-Land post-processed daily statistics have been released as datasets in the new Climate Data Store, replacing the legacy ERA5 daily statistics application.

Did Copernicus Climate Data Store completely borked #ERA5? I'm downloading monthly data and the date information is bonkers. The coordinate is now called "date" (instead of time) and it's not a real time with units, it's just ISO dates as integers. It's impossible to correctly process with CDO and ncivew is throwing a fit.

Oh guck. #Era5 von Copernicus ist auch nicht von Helene betroffen und hat die letzten 2 Monate auch kein Plateau und auch zuletzt keine Steigerung https://pulse.climate.copernicus.eu
Ist interaktiv. Muss man die Kachel Sea Surface Temperature anklicken, sonst sieht man eingangs die air temperature.
#CopernicusClimate is digitising historical climate data from Africa, enhancing reanalysis datasets like #ERA5 via a new data rescue portal developed with WMO.
👆 A valuable resource for researchers and policymakers.

RT by @EUClimateAction: 🌡️🌍According to #ERA5 data, July 2024 was the second warmest July globally, 1.48°C above the estimated July average for 1850-1900 and marking the end of a series of 12 consecutive months at or above 1.5°C.
