“…While the current operational geostationary systems have provided frequent observations based on their equatorial positions, higher latitudes suffer from poor spatial coverage. However, the Russian Arctica satellites, such as the hydrometeorological satellite Arctica-M N1 that launched on 28 Feb 2021 [217], are placed in a highly elliptical Molniya orbit. This orbit provides quasi-geostationary-like imagery over the northern higher latitudes while the satellite is over the pole.…”

The measurement of global precipitation is important for quantifying and understanding the Earth’s systems. While gauges form the basis of conventional measurements, global measurements are only truly possible using satellite observations. Over the last 50–60 years, satellite systems have evolved to provide a comprehensive suite of observing systems, including many sensors that are capable of precipitation retrievals. While much progress has been made in developing and implementing precipitation retrieval schemes, many techniques have concentrated upon retrievals over regions with well-defined precipitation systems, such as the tropics. At higher latitudes, such retrieval schemes are less successful in providing accurate and consistent precipitation estimates, especially due to the large diversity of precipitation regimes. Furthermore, the increasing dominance of snowfall at higher latitudes imposes a number of challenges that require further, urgent work. This paper reviews the state of the current observations and retrieval schemes, highlighting the key factors that need to be addressed to improve the estimation and measurement of precipitation at mid-to-high latitudes.
