SLR (AD) [Prev] [Next]

Scaled Linear Retrievals - processed for every August since 2009, and every month from Jan2017 - May2019

Bug in CFC-11, NO2 and CCL4 Jacobians. Will recalculate data.

RFM (AD) [Prev]

Still working on RFM v5.10 which is a major update with a number of new features. In particular the ability to include 1st order line coupling using coefficients (theoretically) available from the HITRAN database.

IMS (LV) [Prev]

Taking over CH4 processing from DK, comparing core and extended IMS.

Getting hold of recent CAMS and TCCON data for comparisons

CH4 (DK) [Prev] [Next]

Running CH4 and IMS processing to ensure there is a back-up CH4 dataset.

Comparisons of IASI MetOp B and S5P CH4.

NRT (DK) [Prev] [Next]

Data acquisition problems recently, but running again for MetOp B.

Australian Fires (RS) [Prev] [Next]

Working on Australian fire signatures from 2020 - CO, NH3, CH3OH (with Richard Pope). Looking at residual spectra which have high cost.

SO2 (IT) [Prev] [Next]

SO2 from Raikoke failing where there is a high column amount, so trying to use separate v1 and v3 bands. But using v1 alone seems to work better. Possible that v3 is saturating.
