Global daily satellite observations of formaldehyde (HCHO) total vertical column density, gridded at a 0.25x0.25 degree resolution. The OMHCHOG product bins pixel-level data from the OMI/Aura instrument without averaging, preserving raw data points for user-defined filtering. Scientists can use this Level-2G product to generate custom Level-3 global maps for atmospheric chemistry research.
Data is stored in HDF-EOS5 format, which may require specific libraries for access. The listed future update date (2026) suggests metadata may not be current.
