Data sets

Historical 10-minute station observations of solar incoming radiation, longwave downward radiation and sunshine duration for Germany DWD Climate Data Center (CDC) https://opendata.dwd.de/climate_environment/CDC/observations_germany/climate/10_minutes/solar/recent/

Short summary

Ships are an important source of key pollutants. Usually, these are measured aboard the ship or on the coast using in situ instruments. This study shows how active optical remote sensing can be used to measure ship emissions and how to determine emission rates of individual ships out of those measurements. These emission rates are valuable input for the assessment of the influence of shipping emissions in regions close to the shipping lanes.
