Geospace Environmental Datasets

GEOSPACE Geospatial Metadata Catalog v1.4.0

This archive documents a comprehensive catalog of geospatial datasets curated for environmental modeling, ecological analysis, and human impact assessment across the continental United States (CONUS). The catalog provides complete metadata and processing capabilities for 41 variables from several data sources:

MODIS Satellite Data (4 variables) Land surface temperature, vegetation indices (NDVI, EVI), and forest cover

ECMWF ERA5 Reanalysis (14 variables)
Temperature, precipitation, pressure, humidity, wind components, and atmospheric parameters

GridMET Meteorological Data (17 variables) Climate variables, fire weather indices, drought indicators, and evapotranspiration

CAMS Air Pollution Data (6 variables) PM2.5, PM10, NO2, SO2, CO, and ground-level ozone from Copernicus Atmosphere Monitoring Service High-resolution atmospheric composition data for air quality analysis

EPA AQS - US Environmental Protection Agency air quality data (7 variables) PM2.5, PM10, NO2, SO2, CO, O3, and Lead (Pb)

Enhanced Features in v1.4.0:

• Support for 7 NAAQS criteria pollutants (PM2.5, PM10, Ozone, NO2, SO2, CO, Lead)
• Download framework with EPA AQS API integration
• Processing pipeline: JSON → CSV with quality control and column standardization
• County-level, site-level, and state-level geographic filtering

Each dataset entry includes comprehensive metadata with processing script aliases, spatial/temporal specifications, and framework integration details. All processing scripts are linked to version-specific GitHub repositories ensuring reproducible research workflows.

This catalog serves as both a reference document for researchers and a foundation for the GEOSPACE processing framework, enabling automated download and analysis-ready data preparation across multiple Earth observation, climate, and atmospheric composition data sources.
