AQS contains data from all 50 states, the Virgin Islands, Guam, Puerto Rico, and data from border sites in Mexico and Canada. AQS has data available from 1957 to the present day consisting primarily of hourly and 24-hour samples. +
D
About half of the datasets are global scale, a third are US-scale, while some datasets are for other regions. Most datasets are multi-year in extent. About a ten datasets are near-real-time. +
C
CASTNET sites are located throughout the United States, with the best spatial coverage in the East. Many CASTNET sites have been collecting data for 15+ years. The filter pack collects weekly samples of particulate and gaseous data while the ozone monitor records hourly averages at each site. +

Temporal varies with dataset, but 10 years of AQS, latest NEI inventory, etc. Spatial coverage is entire US at county level +
C
The spatial and temporal coverage of CMAQ applications is user-defined. CMAQ applications by the US EPA typically cover national spatial scales at 36 x 36 km and regional scales at 12 x 12 km resolution. Temporal scales range from episodic to annual. The US EPA 2002 CMAQ dataset is based on modeling at 12 x 12 km resolution for the full year of 2002. +
