Erratum to: Foreword: International Space Science Institute (ISSI) Workshop on the Earth’s Hydrological Cycle

Abstract

On the first page of the original article one of the sentences reads: In comparison, the total amount of water vapor in the atmosphere is small; it amounts to *2.5 kg/m, or the equivalent of 25 mm water for each column of air. It should have read: In comparison, the total amount of water vapor in the atmosphere is small; it amounts to *25 kg/m, or the equivalent of 25 mm water for each column of air. Everything else in the paper remains correct.
