For example, in the database of local meteorological stations, if you have access.

You can find a database of irradiation in colorado (usa)

ENERGYDATA.INFO is an open data platform providing access to datasets and data analytics that are relevant to the energy sector. Projects are funded by World Bank’s Energy Sector Management Assistance Program (ESMAP) and focus on the assessment of wind, solar, and biomass resources, including ground-based data collection, geographic information system analysis, and geospatial planning. You will find high-resolution data for some sites as well.

There are many potential sources available, but all depends on:

- Region of interest

- Time period

- Only global irradiance (GHI) or also its direct and diffuse components

- Measured or modeled data?

Dear Aurko Mitra ,

I agree with Piotr Olczak , soda is an impressive data base.

Maybe explore NREL, they also have irradiance profiles.

You can check the NREL site

Data from a nearby local weather station. Not further than 25-30 km. In Internet databases, if there is no local station data, interpolation and extrapolation are used for long distances - several hundred km (up to 500 km). For this reason, the accuracy is not high. Typically, the data recording interval is 10 min.

You can visit the Website of NREL for your answer

I hope it helps.

Goodluck!

Dear Mitra

you can find this data in CAMS service :

Kind regards,

I don't know if anyone has mention it before but you can check cmsaf data if your region is inside meteosat disk area. SIS, DNI and SID irradiance are available with instantaneous and hourly mean temporal resolutions in 0.05x0.05º or 0.03x0.03 grids.

https://wui.cmsaf.eu/safira/action/viewProduktSearch;jsessionid=516BCC778624EEA00402284C96A70BD1.ku_1

Also within nasa ges disc you can fins GLDAS model with 3hour measurements but worst spatial resolution: 0.25x0.25º (https://disc.gsfc.nasa.gov/datasets/GLDAS_NOAH025_3H_2.1/summary) and this data is also available through Google earth engine with temporal coverage until 2020-12-18 together with ERA 5-Land reanalysis (https://developers.google.com/earth-engine/datasets/catalog/ECMWF_ERA5_LAND_HOURLY?hl=en).

If you have access (to data), the nearest weather station to you. The distance should be no more than 25-50 km. I found that I replied again, sorry.

I think there are websites that provide weather data in a general way. the second possibility is to contact the meteorological station in your region directly.
