Short Tutorial on using NASA’s GIOVANNI web tool to create regional-scale time series

Tong, Daniel; Shen, Suhung; Wei, Jennifer

Satellite observations can provide useful information on long term changes in air quality. One of the most widely used satellite products is tropospheric NO₂, which has been retrieved from several different satellite sensors. We provide here a quick tutorial on using Giovanni to analyze a trend in tropospheric NO₂ data, from the NASA Ozone Monitoring Instrument (OMI) sensor, over a region of interest.
