Atmospheric Carbon Monoxide Data Access and Tools

From discovery to visualization, data tools such as the MOPITT Search and Subsetting Web Application, NASA’s Air Quality and Climate Anomaly Viewer, and the Wisconsin Horizontal Interpolation Program for Satellites (WHIPS) guide users in making the most of atmospheric carbon monoxide data.

Commonly Used Carbon Monoxide Data at a Glance

Descriptions of these measurements will be reviewed in more detail later in this Data Pathfinder. The following sections will help guide you to topic-specific data and resources for accessing, visualizing, preparing/manipulating (e.g. subsetting), and analyzing data. Each observation, model, and reanalysis data has unique characteristics that should be considered when evaluating its use.

An asterisk (*) next to an entry indicates that near real-time (NRT) data products are available through NASA's Land, Atmosphere Near real-time Capability for EOS (LANCE). While not intended for scientific research, NRT data are good resources for monitoring ongoing or time-critical events. To learn more about the difference between NRT and Standard Science Products, see Near Real Time versus Standard Products.
