BrO and HO2 pre-average radiances products

Data acquired by the Microwave Limb Sounder on the Aura satellite

BrO and HO2 pre-average radiances products

Monthly zonal mean for January 2005 of MLS BrO observations for three datasets discussed in Millán et al. (2012). Both ascending (mainly daytime) and descending (mainly nighttime) phases of the orbit are shown.

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 and ML3DZMHO2.  Users are urged to read their data quality documents (available from the same location) and contact the MLS science team with any questions.
