Abstract The steps on Verner Suomi's path to becoming a research scientist are examined. We argue that his research style—his natural interests in science and engineering, and his methodology in pursuing answers to scientific questions—was developed in his youth on the Iron Range of northeastern Minnesota, as an instructor in the cadet program at the ...

Joint spectral retrievals of ozone with Suomi NPP CrIS augmented by S5P/TROPOMI
Atmospheric Measurement Techniques. The vertical distribution of ozone plays an important role in atmospheric chemistry, climate change, air pollution, and human health. Over the 21st century, spaceborne remote-sensing methods and instrumentation have evolved to better determine this ...

A Unified Cloud Detection Method for Suomi-NPP VIIRS Day and Night PAN Imagery
IEEE Transactions on Geoscience and Remote SensingCloud detection is a necessary step before the application of remote sensing images. However, the radiation intensity similarity between artificial lights and clouds is higher in nighttime remote sensing images than in daytime remote sensing images ...
