This dataset shows high-resolution (0.1×0.1 degree) monthly mean Tropospheric NO2 values acquired by Ozone Monitoring Instruments (OMI) on the NASA Aura satellite from 2006 to 2016. Nitrogen dioxide is a gaseous air pollutant produced by vehicle emissions and other fossil fuel combustion processes such as coal-fired electrical plants or biomass burning. Globally, the greatest NO2 emissions are from industrial areas and high-population urban centers. NASA measures and monitors NO2 because it contributes to the formation of other air pollutants, such as ozone.

This 10-year animation compliments aerial data collected by the 2017 Lake Michigan Ozone Study (LMOS 2017) which commenced in May 2017 with flights along the shores of western Lake Michigan. The campaign provides extensive observational air quality and meteorology datasets through a combination of airborne, ship, mobile lab, and fixed ground-based observational platforms. The goal of the study is to better understand ozone formation and transport around Lake Michigan; in particular, why ozone concentrations are generally highest along the lakeshore and drop off sharply inland and why ozone concentrations sometimes peak in rural areas far from major emission sources.
LMOS 2017 measurements will provide critical observations for evaluating a new generation of air quality models attempting to better simulate ozone episodes in the region. Over the long term, the information collected is expected to result in:
- Improved modeled ozone forecasts for this region, which states and EPA use to meet state and federal Clean Air Act
- Better understanding of the lakeshore gradient in ozone concentrations
- Improved knowledge of how emissions influence ozone formation in the region.

The December 2016 through February 2017 seasonal global temperature was 1.6 °Fahrenheit, or 0.89°Celsius above the 20th century average of 53.8°Fahrenheit – the second highest ever recorded – just slightly behind 2015/2016.
The United States had its’ sixth warmest and eighth wettest winter on record.
The December through February average sea surface temperature was also the second warmest ever recorded.
One of the top weather stories was drought “disappearing act” of the drought footprint across the United States, due largely to repeated atmospheric rivers directed at the west coast, and also, streaming north from the Gulf of Mexico over the southeast U.S.
The quarterly climate digest, produced seasonally, consists of a short movie (3:02 minutes) made for SOS and an MP4 video accessible through YouTube.

NOAA’s newest geostationary satellite, GOES-16 carries breakthrough technology, including the Advanced Baseline Imager (ABI) that measures 16 channels of the electromagnetic spectrum! To put this in perspective, current operational GOES measures 5 channels, or 5 spectral bands, of the electromagnetic spectrum.
This short movie for SOS, available for preview on YouTube advances sequentially through each channel of preliminary, non-operational imagery acquired by GOES-16 ABI on March 7, 2017 two full times, both without audio. During the first sequence, a white arrow points to the part of the electromagnetic spectrum where ABI is collecting data. You can also see the numerical value of the channel/band in micrometers (µm), band type, primary purpose, and the band “nicknames” as assigned by the GOES-R program.
The second time through, we see the full disk image with only the band nicknames and the numerical value of the spectral band.
