Another aspect of our non-profit environmental commitment is our support for climate research through the Initiative Pro Klima. The aim of this research project, which we have funded, is to better understand the impact of climate change and derive conclusions for environmentally friendly action. The OceanRAIN project (Ocean Rain And Ice-phase precipitation measurement Network for surface validation) carried out by the University of Hamburg’s CliSAP excellence cluster is one of the climate protection projects sponsored by the Initiative. The objective is to investigate the relationship between climate change and precipitation by long-term measurement of precipitation on the world’s oceans. Therefore, satellite data has to be reviewed. To collect the data, a total of nine research vessels from various countries, seven of which currently have a long-term focus, are equipped with precipitation gauges called disdrometers. Disdrometers are instruments that individually optically record every drop of rain or each snowflake and from this separately calculates the amount of rain or snowfall per square meter. In 2015, further milestones were achieved in the research project. Besides the precipitation rate, OceanRAIN now also calculates the evaporation rate along the ship's lanes. The difference between these values, called the freshwater flow, is a sensitive climatic parameter and is systematically measured for the first time in our data set. New national and international cooperation enables long-term installations in previously uncharted waters: The American research vessel Roger Revelle is systematically traversing the tropical Pacific Ocean with a disdrometer and the luxury cruise ship The World travels to destinations around the world with our device on board. Systematic measurements on board the Australian icebreaker Aurora Australis are in preparation, for examining the oceans around the Antarctic.
