Surface Pressure (SP) – Mean Surface Atmospheric Pressure

Global | ~1 km Resolution | 2020–2024


Short Description

This dataset represents the spatial distribution of mean surface atmospheric pressure (SP), which influences air density and atmospheric conditions affecting solar radiation transmission.


Technical Specification

The dataset is derived from ERA5 surface pressure (SP) fields and represents mean surface atmospheric pressure for the period 2020–2024.

ERA5 hourly pressure 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.


Key Characteristics

  • Units: pascals (Pa)
  • Represents mean surface atmospheric pressure
  • Derived from ERA5 surface pressure fields
  • Represents climatological mean conditions for 2020–2024

Spatial Characteristics

  • Coordinate System: GCS_WGS_1984
  • Native Resolution: ~0.25°
  • Resampled Resolution: ~1 km (30 arc-second)
  • Coverage: Global (±85.0511° for web compatibility)

Role in SSI™ Model

Surface pressure (SP) is one of several atmospheric variables incorporated into the Solar Suitability Index (SSI™) model developed by AtmosphericIQ LLC.

As a determinant of air density and atmospheric mass, surface pressure influences radiative transfer, scattering processes, and environmental conditions, 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

  • Atmospheric and climatological analysis
  • Environmental and exposure modeling
  • Radiative transfer and air density studies
  • 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.
