2-Meter Air Temperature (T2M) – Mean Near-Surface Air Temperature
Global | ~1 km Resolution | 2020–2024
Short Description
This dataset represents the spatial distribution of mean near-surface air temperature (T2M), measured at 2 meters above ground level. Air temperature influences atmospheric conditions, material performance, and environmental processes affecting solar suitability.
Technical Specification
The dataset is derived from ERA5 2-meter air temperature (T2M) fields and represents mean near-surface air temperature for the period 2020–2024.
ERA5 hourly temperature values were aggregated across the 2020–2024 period to produce a multi-year climatological mean.
This dataset is developed by AtmosphericIQ LLC and processed for distribution and deployment by Engineering Director, Inc.

Role in SSI™ Model
2-Meter Air Temperature (T2M) is one of several atmospheric variables incorporated into the Solar Suitability Index (SSI™) model developed by AtmosphericIQ LLC.
As a key environmental parameter, air temperature influences atmospheric density, thermodynamic conditions, and system performance, contributing to the overall SSI™ suitability scoring framework.
This dataset is provided as a supporting climatic input layer and does not independently represent solar suitability.
Applications
- Climatological and environmental analysis
- Solar system performance context
- Material and environmental exposure modeling
- Geospatial screening workflows
Data Source
Derived from Copernicus Climate Change Service (C3S) ERA5 reanalysis data, with processing including temporal aggregation (2020–2024), spatial resampling to ~1 km resolution, and web-compatible clipping.
