New MLS Level 3 (v4) BrO and HO2 pre-average radiances products
The science team for the Microwave Limb Sounder (MLS) on the Aura satellite is pleased to announce the release of new bromine monoxide (BrO) and hydroperoxyl (HO2
) MLS "Version 4" pre-average radiances datasets. The retrieval algorithm produces a pair of zonal mean abundance fields each day - one for the daytime part of the orbit and the other for the nighttime part - from 10o
latitude bin zonal mean radiances. By sacrificing spatial resolution, the noise level and the biases in the retrieved profiles are greatly reduced.
Notable advantages over the standard level 2 products include the first long-term nighttime HO2
satellite record and a wider pressure range (21 - 0.003 hPa) for the HO2
dataset (the standard Level 2 product covers only 21 - 0.046 hPa). Further information can be found at Millán et al. (2012) and Millán et al. (2015).
These new datasets are available at the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC): ML3DZMBRO
. Users are urged to read their data quality documents (available from the same location) and contact the MLS science team with any questions.
