Short Name:

MLS/Aura Level 3 Daily Binned Nitric Acid (HNO3) Mixing Ratio on Zonal and Similar Grids V004 (ML3DZHNO3) at GES DISC

ML3DZHNO3 is the EOS Aura Microwave Limb Sounder (MLS) daily binned on zonal and assorted vertical grids product for nitric acid (HNO3) derived from radiances measured by the 240 GHz radiometer at and below 10 hPa, and from the 190 GHz radiometer above 10 hPa. The data version is 4.2. Data coverage is from August 2, 2004 to current. Spatial coverage is near-global (-82 to +82 degrees latitude) at 4 degree latitude zonal increments. The recommended useful vertical range is from 215 to 1.47 hPa (1.0 hPa under enhanced conditions), and the vertical resolution is between about 3 and 5 km. Users of the ML3DZHNO3 data product should read chapter 4 and section 3.12 of the EOS MLS Level 2 Version 4 Quality Document for more information. The data files contain one year of data and are archived in the netCDF4 format, which is also compatible with HDF5 readers and tools. Each file contains four group objects: lat vs pressure zonal mean, lat vs "potential temperature" zonal mean, "equivalent latitude" vs "potential temperature" zonal mean, and vortex average vs "potential temperature". Each group has a set of data (average, min, max, std dev, rms) and geolocation fields, grid attributes, and metadata.
