A systematic assessment of water vapor products in the Arctic: from instantaneous measurements to monthly means
Water vapor is an important component in the water and energy cycle of the Arctic. Especially in light of Arctic amplification, changes in water vapor are of high interest but are difficult to observe due to the data sparsity of the region. The ACLOUD/PASCAL campaigns performed in May/June 2017 in t...

Water vapor is an important component in the water and energy cycle of the Arctic.
