NASA TEMPO

Description

Part of NASA’s EARTHDATA portal, providing access to downloadable satellite observations from the Tropospheric Emissions: Monitoring of Pollution (TEMPO) mission.

Questions this resource can help answer

What is the spatial and temporal pattern of ozone, formaldehyde, and nitrogen dioxide over North America?

How do I use this resource?

This resource provides downloadable files of column observations for NO2, ozone, formaldehyde, and trace gases. Use of this resource requires understanding of satellite data. Downloadable data is in Network Common Data Form (netCDF), a binary file format. You can view the data using NASA Panoply, GIS software, and with Python or R. When you choose a “collection” of data to download it will bring up a set of individual “granule” files. You can download an individual hourly file, or an entire collection of the granules.

Pro tips

When you bring up the resource, it will offer you a tour of Earthdata Search. Take the tour and then come back to the resource. It will help. The term “granules” refers to the smallest unit of data from a satellite instrument, which together make up a larger data collection.

Methodology

Nitrogen dioxide Level 3 (PROVISIONAL) files provide trace gas information on a regular grid covering the TEMPO field of regard for nominal TEMPO observations. Level 3 files are derived by combining information from all Level 2 files constituting a TEMPO East-West scan cycle. The files are provided in netCDF4 format, and contain information on tropospheric and stratospheric nitrogen dioxide vertical columns, ancillary data used in air mass factor and stratospheric/tropospheric separation calculations, and retrieval quality flags.

Total ozone Level 3 files provide ozone information on a regular grid covering the TEMPO field of regard for nominal TEMPO observations. Level 3 files are derived by combining information from all Level 2 files constituting a TEMPO East-West scan cycle. The files are provided in netCDF4 format, and contain information on total column ozone and some auxiliary derived and ancillary input parameters including effective cloud fraction, effective cloud pressure, radiative cloud fraction, SO2 index, and terrain pressure

Model

GEOS-Chem

GEOS-Chem is an open?source global 3?D chemical transport model used to simulate atmospheric composition, including gases and aerosols, and their chemistry, transport, and deposition. The website provides documentation, installation and run instructions, tutorials, model version information, input datasets, and links to the user community and developer resources. Researchers use it to run simulations for air quality, climate, and biogeochemical cycling studies, and to contribute improvements back to the shared codebase.

Model

Hazardous Air Pollutant Exposure Model (HAPEM)

EPA’s HAPEM (Hazardous Air Pollutant Exposure Model) is a human exposure model that estimates how people are exposed to outdoor-origin hazardous air pollutants as they move through different microenvironments (home, work, in transit, outdoors). Using ambient concentration inputs, population and activity-pattern data, and microenvironmental factors (e.g., infiltration indoors), HAPEM produces distributions of exposure for various population groups and is used in national? and regional?scale risk assessments such as the National Air Toxics Assessment.

Human Exposure Model (HEM)

EPA’s Human Exposure Model (HEM) is a probabilistic exposure assessment tool used to estimate how people are exposed to contaminants (often air pollutants, but not limited to them) through different pathways and microenvironments. It is designed to support human health risk assessments by translating environmental concentrations into population exposure distributions for specific pollutants, locations, and demographic groups. HEM uses information on contaminant levels, population characteristics, and time–activity patterns to produce quantitative estimates of average and high-end exposures suitable for regulatory analyses and comparative policy evaluations.
