Request via CDS
Select variables, date range, and a bounding box. NetCDF Studio submits your request to the Copernicus CDS and tracks queue position automatically.
Download ERA5 and Convert to CSV
ERA5 is ECMWF's global reanalysis — 0.25° resolution, hourly, from 1940 to near-present. Getting data out normally means writing a cdsapi script, waiting in a queue, then converting NetCDF yourself. NetCDF Studio does all three: choose variables, dates and a region, and receive a CSV.

PROCESSING PIPELINE
How It Works
Download & Convert
Once the CDS job completes, NetCDF Studio downloads the NetCDF file and converts it — applying any selected correction modules in one pass.

Your CSV is ready in your workspace — one row per grid cell per time step, SI units, ISO 8601 timestamps. Opens in Excel, QGIS, R and Python.
FAQ
Common Questions
Do I need a Copernicus account?
Yes. ERA5 is distributed by Copernicus and requires your own free personal access token. You add it once in Settings; it is encrypted at rest and is never written to logs or returned by the API.
How long does an ERA5 request take?
Most of the wait is queue time inside the Copernicus CDS, which is outside our control and can run to tens of minutes for large requests. The job reports which stage it is in — queue, downloading, or converting — rather than a fake progress bar.
Can I request only part of the globe?
Yes, and you should — a bounding box is passed to Copernicus with the request, so only the region you asked for is ever downloaded. That makes the job dramatically faster and the resulting file much smaller.
Can I apply correction modules to ERA5 output?
Yes. All NetCDF Studio correction modules work with ERA5 data — temperature unit conversion, radiation integration, FAO-56 evapotranspiration, wind speed normalisation, and more.
