Matthew Shupe

Matthew David Shupe (born around 1975 in Washington, D.C., US) is an American mathematician, chemist, meteorologist and climatologogist.

Life
Matthew Shupe was born in Washington state but grew up in Idaho. He attended college in Colorado. After that, he studied mathematics and chemistry with a focus on atmospheric sciences at the University of Puget Sound in Washington state. He completed his studies in 1997 with a bachelor's degree in chemistry and mathematics.

In 1996, he worked as a research assistant at the Pacific Northwest National Laboratory in Richland, Washington. From 1998 to 2004, he was a research scientist at the Environmental Technology Laboratory of the National Oceanic and Atmospheric Administration (NOAA). Since 2004, he has been a research associate at the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder and the Earth System Research Laboratory (ESRL) at NOAA.

In 2006, he received master's degree in astrophysics and atmospheric sciences from the University of Colorado Boulder. In 2007, he received his doctorate there with a thesis on An intricate balance of liquid and ice: The properties, processes, and significance of Arctic stratiform mixed-phase clouds.

From 2019 to 2020, he was a co-leader of the MOSAiC Expedition together with Klaus Dethloff and expedition leader Markus Rex. In leg 1 of MOSAiC (from 20 September 2019 to 13 December 2019) and leg 4 (from 8 June 2020 to 9 August 2020), Shupe was on board the research vessel Polarstern. During these periods, he led the Atmosphere team and was a member of the Communications / Outreach and Data teams.

Shupe is married and has two sons.

Research
Shupe's research focuses on the microphysical, radiational, and dynamic properties of clouds. He works with the interactions at boundary layers and surfaces. He evaluates the parameterizations of cloud models and classifies cloud types. He researches the meteorology and climate of the Arctic.

Through his research, Shupe aims to understand the variability and changing nature of the Arctic climate system. He specifically researches the role played by clouds, atmospheric structure, and the energy exchange of surfaces. He observes the melting of sea ice and glaciers. He collects data about the ice on land and in the ocean. This creates a physical understanding that should help improve climate models.

Shupe discovered that clouds in which the water is liquid occur in the Arctic, even though they are much colder than zero degrees Celsius. They don't freeze into ice because there are no condensation nuclei. These cold, liquid clouds have a very strong influence on atmospheric radiation. This influence had not previously been properly taken into account in climate models.

Research projects and expeditions
In various capacities, Shupe took part in the following projects:
