Background

The launch of the Tropospheric Emissions: Monitoring Pollution (TEMPO) mission (April 2023) provides key measurements of trace gas constituents over North America from a geostationary orbit. These observations are important to the air quality forecasting and regulatory communities. Survey respondents requested a subset of the currently planned TEMPO products be expedited to near real-time (NRT) availability to assist in forecasting and modeling efforts. Other products are requested to be added using robust science algorithms adapted from other sensors with similar capabilities.

Status

This activity is currently in pre-formulation and will include developing a new hourly sulfur dioxide (SO₂) concentration product from TEMPO. This activity will also adapt established science algorithms from NASA’s Ozone Monitoring Instrument to produce additional trace gas measurements from TEMPO (SO₂, ultraviolet aerosol optical depth (UVAOD), aerosol height, water (H₂O), ultraviolet B radiation (UVB), glyoxal (CHOCHO), and bromine monoxide (BrO)).​

Solution Characteristics

Societal Impact

This activity will provide low-latency SO₂ data to enable real-time monitoring of volcanic plumes as well as science-quality aerosol and trace gas products to support air quality forecasting, modeling, and regulation.
