We are pleased to announce that a new dataset has been published today, 03 June 2025, in the Climate Data Store (CDS):

[ERA5 Land hourly time-series data from 1950 to present  
 ](https://cds.climate.copernicus.eu/datasets/reanalysis-era5-land-timeseries?tab=overview)

This dataset is **a subset of some parameters** of the full [CDS ERA5-Land hourly dataset](https://cds.climate.copernicus.eu/datasets/reanalysis-era5-land?tab=overview) on 0.1 degrees resolution and is stored in [Analysis Ready Cloud Optimised (ARCO)](https://blog.lobelia.earth/arco-the-smartest-way-to-access-big-geospatial-data-eaf689eff3c9) format, which has been implemented for retrieving long time-series for a single point in a efficient way.  
Please be aware that this is an experimental catalogue entry which uses an alternative source for the ERA5-Land data designed for fast access long-timeseries for a single point, and **it is not recommended for use in operational systems**.

**Please note** the variables such as “Total precipitation” and “Surface solar radiation downwards” have been de-accumulated.

For any enquiries regarding this dataset or the application, please [contact us](https://climate.copernicus.eu/help-and-support).

Hi @Michela , nice to have this way to select data, however, it looks like if one wants to analyse a small rectangular area, say 1x1 degree, they must run this request 100 times?

Would it not make sense to allow the user to specify a coordinate of choice and then perform spatial interpolation to combine several grid points, rather than force the user to choose a multiple of 0.1 degrees?
