Daily Surface Air Temperature

This page provides time series and map visualizations of daily mean surface air temperature (2-meter height) estimates from the #ECMWF Reanalysis version 5 (#ERA5) for the period January 1940 to present (see ERA5 attribution below). ERA5 is a state-of-the-art numerical #climate / #weather modeling framework that ingests surface, radiosonde, and satellite observations to estimate the state of the atmosphere through time. The visualizations on this page enable users to explore weather-driven temperature changes within specific years, while also having several decades of daily data for broader climate context. Users are encouraged to learn more about reanalysis — approach, strengths, limitations, and product comparisons — from the NCAR Climate Data Guide. Additional information about reanalysis can be found at Advancing Reanalysis.

Question: Is anyone here familiar with the #ERA5 dataset used for the climate data at #OpenMeteo ?

I intend to use it for the local elections for my local #Green Party chapter, by visualizing local climatic changes. And I need to be ready for arguments on the lines of:

"This data is interpolated, therefore not real and thus can be dismissed!"

Thus, if there are any good, accessible explanations that summarize how the dataset was created, I would appreciate it. Bonus points if they are in German!

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?

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.

https://www.copernicus.eu/en/media/image-day-gallery/august-2025-third-warmest-august-record-globally

#Klimawandel #ERA5 #C3S #Hitze

@ZLabe can you notice any signals in the #ERA5 sea ice? It's switched to an AMSR2 derived product as of the start of the month

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.

https://climate.copernicus.eu/surface-air-temperature-may-2025

#Klimawandel #GlobaleErwärmung #Temperaturrekorde #Klimadaten #ERA5 #C3S #Mai2025

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.

Read more about the latest findings in our #C3S Monthly Bulletin: https://climate.copernicus.eu/2nd-warmest-april-globally-remains-15degc-above-pre-industrial-level?utm_source=socialmedia&utm_medium=ma&utm_campaign=2nd-warmest-april-globally-remains-15degc-above-pre-industrial-level

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.

#python #grib #netcfd #ERA5

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.

Direct link 👉 https://cds.climate.copernicus.eu/datasets/reanalysis-era5-single-levels-timeseries?tab=overview

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.

#ClimateScience
#Copernicus

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?
All the answers: https://climate.copernicus.eu/what-degree-uncertainty-c3s-daily-global-temperature-data

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