3.1) Operational TROPOMI and COBRA products around Nikola Tesla (Serbia)
.
•
• Operational and COBRA products are different → challenging for validation with airborne measurements
Flight track was designed to allow for satellite evaluation in space and time; due to fog the flight was delayed
by two hours and took place from ~13:30 to 14:30 UTC

*COBRA is mostly meant to improve the low SO2 VCDs (<~0.25DU) and therefore not performing the
retrievals for the alternative windows (325-335 nm and 360-390nm) as in the operational algorithmView entire presentation
