High-resolution Tropospheric NO<sub>2</sub> Retrieval over Asia based on OMI POMINO v2.1 and quantitative comparison with other products

A high-resolution and observationally constrained OMI NO2 satellite retrieval

This work presents a new high-resolution NO2 dataset derived from the NASA Ozone Monitoring Instrument (OMI) NO2 version 3.0 retrieval that can be used to estimate surface level concentrations. The standard 15 NASA product uses NO2 vertical profile shape factors from a 1.25° × 1° (~110 × 110 km) resolution Global Model Initiative (GMI) model simulation to calculate air mass factors, a critical ...

Near-real time retrieval of tropospheric NO2 from OMI

We present a new algorithm for the near-real time retrieval – within 3 h of the actual satellite measurement – of tropospheric NO2 columns from the Ozone Monitoring Instrument (OMI). The retrieval is based on the combined retrieval-assimilation-modelling approach developed at KNMI for off-line tropospheric NO2 from the GOME and SCIAMACHY satellite instruments. We have adapted the off-line syste...

Tropospheric ozone column retrieval from OMI data by means of neural networks: a validation exercise with ozone soundings over Europe

The retrieval of the tropospheric ozone column from satellite data is very important for the characterization of tropospheric chemical and physical properties. However, the task of retrieving tropospheric ozone from space has to face with one fundamental difficulty: the contribution of the tropospheric ozone to the measured radiances is overwhelmed by a much stronger stratospheric signal, which...

Three-way comparison between OMI and PARASOL cloud pressure products

[1] The cloud pressures determined by three different algorithms, operating on reflectances measured by two spaceborne instruments in the ‘‘A’’ train, are compared with each other. The retrieval algorithms are based on absorption in the oxygen A-band near 765 nm, absorption by a collision induced absorption in oxygen near 477 nm, and the filling in of Fraunhofer lines by rotational Raman scatte...
