Long‐Term Photovoltaic System Performance in Cold, Snowy Climates

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
We review degradation rates of photovoltaic systems located in cold humid continental, subarctic, and tundra climates and analyze three new photovoltaic systems > 60° N in Alaska and Canada with each with between 5 and 16 years of data. Overall, PV systems located in cold climates have a median degradation rate of −0.33%/year.

Atmospheric River Impacts on Greenland Ice Sheet Surface Mass Balance

open access: yesJournal of Geophysical Research: Atmospheres, 2018
Greenland Ice Sheet (GrIS) mass loss has accelerated since the turn of the twenty‐first century. Several recent episodes of rapid GrIS ablation coincided with intense moisture transport over Greenland by atmospheric rivers (ARs), suggesting that these ...

Automatic identification of streamlined subglacial bedforms using machine learning: an open‐source Python approach

open access: yesBoreas, EarlyView.
Morphometric values of streamlined subglacial bedforms provide valuable information about the relative speed, direction, and maturity of past ice streams. This paper presents a new tool that utilizes a machine learning approach to automatically identify glacially derived streamlined features.

Changes in the Velocity Structure of the Greenland Ice Sheet [PDF]

open access: yesScience, 2006
Using satellite radar interferometry observations of Greenland, we detected widespread glacier acceleration below 66° north between 1996 and 2000, which rapidly expanded to 70° north in 2005. Accelerated ice discharge in the west and particularly in the east doubled the ice sheet mass deficit in the last decade from 90 to 220 cubic kilometers per year.

Impact of ocean stratification on submarine melting of a major Greenland outlet glacier [PDF]

open access: yes, 2011
Submarine melting is an important balance term for tidewater glaciers1,2 and recent observations point to a change in the submarine melt rate as a potential trigger for the widespread acceleration of outlet glaciers in Greenland3-5.

MIS-11 duration key to disappearance of the Greenland ice sheet [PDF]

open access: yes, 2017
Palaeo data suggest that Greenland must have been largely ice free during Marine Isotope Stage 11 (MIS-11). However, regional summer insolation anomalies were modest during this time compared to MIS-5e, when the Greenland ice sheet likely lost less ...

Monitoring of the Greenland ice sheet using a broadband seismometer network: the GLISN project

open access: yesAntarctic Record, 2014
Global climate change is currently causing melting of the Greenland ice sheet. Recently, a new type of seismic event, referred to as a "glacial earthquake", has been recognized.

An inventory of subglacial overdeepenings in southern Germany and Austria

open access: yesBoreas, EarlyView.
We present an inventory and morphometric characterization of >100 individual overdeepened basins in southern Germany and Austria compiled from heterogeneous sources. Arrangement and dimensions of overdeepenings are compared to those of their western Alpine counterparts, to catchment topographies and bedrock lithologies, and to modelled ice‐flow ...

Sulfate and MSA in the air and snow on the Greenland Ice Sheet [PDF]

open access: yes, 1994
Sulfate and methanesulfonic acid (MSA) concentrations in aerosol, surface snow, and snowpit samples have been measured at two sites on the Greenland Ice Sheet.

Reconstructions of the 1900–2015 Greenland ice sheet surface mass balance using the regional climate MAR model

open access: yes, 2016
. With the aim of studying the recent Greenland ice sheet (GrIS) surface mass balance (SMB) decrease relative to the last century, we have forced the regional climate MAR (Modele Atmospherique Regional; version 3.5.2) model with the ERA-Interim (ECMWF ...
