TROPESS CrIS-SNPP L2: Atmospheric Profiles Over Sao Paulo

The TROPESS CrIS-SNPP L2 for Sao Paulo Megacity, Standard Product contains vertical profiles of seven atmospheric gases and temperature retrieved from the Suomi-NPP satellite's CrIS instrument. Data are provided daily from February 2021 onward, covering a 3x3 degree region over Sao Paulo at 14 km spatial resolution across 17 vertical levels. The NASA TROPESS project uses the MUSES optimal estimation algorithm to produce these netCDF files.

Use Cases

• Monitoring urban methane and carbon monoxide emissions based on retrieved CH4 and CO profiles.
• Analyzing vertical ozone distribution and its precursors based on retrieved O3 and PAN data.
• Studying atmospheric water vapor and isotopic composition based on retrieved H2O and HDO profiles.
• Investigating ammonia emissions and transport based on retrieved NH3 profiles.
• Validating atmospheric models with temperature and trace gas profiles across 17 vertical levels.

Strengths

• Provides vertical profiles for seven specific gases (CH4, CO, H2O, HDO, NH3, O3, PAN) and temperature, with formal uncertainties.
• Offers high vertical resolution with data reported at 17 levels from the surface to 0.1 hPa.
• Focuses on a specific, high-impact geographic region (Sao Paulo megacity) with continuous data collection from 2021-02-01 onward.

Limitations

• Column names and exact dataset size (rows) are not provided in the available metadata.
• Spatial coverage is limited to a single 3x3 degree region centered on Sao Paulo.
• The license is listed as 'other-license-specified' without further details.
