A simple physics-based improvement to the positive degree day model [PDF]
Journal of Glaciology, 2018 Meltwater is important to understanding glacier health and dynamics. Since melt measurements are uncommon, ice ablation estimates are often based on models including the positive degree day (PDD) model.

A degree-day model for forecasting adult phenology of Popillia japonica (Coleoptera: Scarabaeidae) in a temperate climate. [PDF]
Front Insect Sci, 2022 Japanese beetle, Popillia japonica (Newman), was first detected in the United States in New Jersey in 1916. The beetle gradually spread to the Midwest U.S. region, and was first confirmed in Minnesota in the late 1960’s.

Improving the degree-day model for forecasting Locusta migratoria manilensis (Meyen) (Orthoptera: Acridoidea). [PDF]
PLoS One, 2014 The degree-day (DD) model is an important tool for forecasting pest phenology and voltinism. Unfortunately, the DD model is inaccurate, as is the case for the Oriental migratory locust.

Estimating degree-day factors from MODIS for snowmelt runoff modeling [PDF]
Hydrology and Earth System Sciences, 2014 Degree-day factors are widely used to estimate snowmelt runoff in operational hydrological models. Usually, they are calibrated on observed runoff, and sometimes on satellite snow cover data.

Estimating degree-day factors of snow based on energy flux components
The Cryosphere, 2023 . Meltwater from mountainous catchments dominated by snow and ice is a valuable source of fresh water in many regions. At mid-latitudes, seasonal snow cover and glaciers act like a natural reservoir by storing precipitation during winter and releasing it
