Positive degree-day sums in the Alps: a direct link between glacier melt and international climate policy

open access: yesJournal of Glaciology, 2022
Annual balances of eight alpine glaciers were slightly negative for 1961–90 and highly negative for 1991–2018. We explain this by changes in positive degree-day sums and summer temperatures extrapolated to the median altitudes of the glaciers.

Differentiating Snow and Glacier Melt Contribution to Runoff in the Gilgit River Basin via Degree-Day Modelling Approach

open access: yesAtmosphere, 2020
In contrast to widespread glacier retreat evidenced globally, glaciers in the Karakoram region have exhibited positive mass balances and general glacier stability over the past decade.

Comparative Study of Hydrology and Icemelt in Three Nepal River Basins Using the Glacio-Hydrological Degree-Day Model (GDM) and Observations From the Advanced Scatterometer (ASCAT)

open access: yesFrontiers in Earth Science, 2020
An assessment of the water supply and its seasonal and annual changes over the century in the High Mountain Asia (HMA) region is of increasing interest due to its potential impact on one-sixth of the global population. In order to understand the changing

Degree-Days [PDF]

open access: yes, 2011
The melting of snow and ice is assumed to be related to air temperature as long as air temperature is above a critical threshold, usually close to the melting point of ice. In particular, the amount of snow or ice melted at a certain place, during a certain period, is assumed proportional to the sum of positive temperatures (on the Celsius scale) at ...

Temperature Effects on Development of Meloidogyne enterolobii and M. floridensis

open access: yesJournal of Nematology, 2022
Meloidogyne enterolobii and M. floridensis are virulent species that can overcome root-knot nematode resistance in economically important crops. Our objectives were to determine the effects of temperature on the infectivity of second-stage juveniles (J2)

Seasonal Correction Factors for the Biotic Index [PDF]

open access: yes, 2017
For evaluation of streams with the biotic index (BI), samples of arthropods should be collected in the spring before degree day accumulations of mean air temperatures above 4.5°C reach 440° in warm-water streams, and before they reach 1050° in cold-water
