Short summary
Lakes affect local weather and climate. This influence should be taken into account in NWP models through parameterization. For the atmospheric simulation, global coverage of lake depth data is essential. To provide such data Global Lake Database (GLDB) has been created. More than 3 thousand in-situ lake depths all over the globe have been added. However over 83 % of newly added data have not been found on global ecosystem map ECOCLIMAP2.
