03_09 known problems• Not working

– Fg_ctrl_sunglint, Fg_ctrl_moonglint, & Fg_ctrl_gal_noise

– Tg_ice_concentration & Tg_suspect_ice– itMax = 0 (for BT’s -> DAP?)

• Polarised galactic noise not implemented• Cannot set processing window (longitude)

across date-line• Too_Few_Measurents_Rejected x2 in SPH

ADFs• AlgoVal has focussed on processor algorithms,

but aux data also important, so...• We need to review ADFs & plan for updates

– How to (re-)make ADFs?– Are the ADFs ok for launch?– Who is responsible for updates?– How are ADFs verified?

• Contains: land-sea mask, distance to coast, monthly sea-ice mask, & Tg_resol_max

• Sea-ice data is 1979-2003 – ok?• Where do these come from?
