Now have data running in approximately NRT for IASI A and B. Running out of
memory space (more RAM required?). Processed linear retrieval for IASI A for
complete archive. Aim to have iterative retrieval in NRT if possible (SO2
heights). CEMS have to order IASI off-line data periodically, so occasionally
gaps develop. Could NRT data be kept until off-line data available? IASI-A NRT
feed not working since last week? VB would like sample netCDF output with a view
to archiving the data. Issue getting ECMWF forecast data for NRT non-linear
processing. Would it be better to use IASI operational T retrievals?

Working on RFM LUTs for different molecules, aiming to model RTTOV ensemble
of 80 atmospheres within 0.1 of nominal IASI across whole IASI infrared range.
CO2 and H2O are particular
problems, eg finding suitable p,T axes (and VMR-axis for H2O).
H2O LUTs are currently huge.
