Ship trails have been perceived as convincing evidence of aerosol-cloud interaction. Ship emissions have been proven to contribute by about 1.9% and 2.9% to the increase in the global total and fine-mode aerosol optical thickness (AOT) respectively over a five year period (Peters et al. 20212).
The ERS programme celebrated its 30th anniversary on 17 July. Today, we are still exploiting ERS data and experts continue to work on improving the altimeter, radiometer and SAR data the programme acquired.
A new GOME Level 1b dataset has been generated for the 16-year mission period bringing relevant quality improvements for the revised calibration approach, compensating aging and instrument degradation, and provide enhanced accessibility.
