Abstract
Annual Surface Mass Balance Records (2009–2019) From an Automatic Weather Station on Mittivakkat Glacier, SE Greenland
Highlights
Quantifying area and volume loss of the world’s glaciers outside the large ice sheets has caught the attention of policy makers and the public due to the potential impact on sea-level rise (e.g., AMAP, 2019; IPCC, 2019; Wouters et al, 2019; Zemp et al, 2019)
The Mittivakkat (MIT) automatic weather station (AWS) is part of the PROMICE network in Greenland, which currently consists of eight regions with two automatic weather stations (AWSs) all located at different elevations (Ahlstrøm et al, 2008)
Mittivakkat glacier covers an area of ca. 32 km2 (e.g., Mernild et al, 2015) and the AWS is located below the long-term equilibrium altitude (ELA), resulting on average in a negative surface mass balance at the AWS site
Summary
Quantifying area and volume loss of the world’s glaciers outside the large ice sheets has caught the attention of policy makers and the public due to the potential impact on sea-level rise (e.g., AMAP, 2019; IPCC, 2019; Wouters et al, 2019; Zemp et al, 2019). The robustness of sea-level rise predictions rely heavily on observational data from glaciers in the world, which is why reliable mass balance measurements are in high demand (AMAP, 2019; IPCC, 2019). A database accessible through the PROMICE data portal (https://www.promice.org/PromiceDataPortal) provides a Greenland wide mass balance data collection with associated background information (Machguth et al, 2016).
