No Consistent Evidence for Advancing or Delaying Trends in Spring Phenology on the Tibetan Plateau [PDF]

open access: yes, 2017
Vegetation phenology is a sensitive indicator of climate change and has significant effects on the exchange of carbon, water, and energy between the terrestrial biosphere and the atmosphere.

A longer vernal window: The role of winter coldness and snowpack in driving spring thresholds and lags [PDF]

open access: yes, 2017
Climate change is altering the timing and duration of the vernal window, a period that marks the end of winter and the start of the growing season when rapid transitions in ecosystem energy, water, nutrient, and carbon dynamics take place.

Complex responses of spring vegetation growth to climate in a moisture-limited alpine meadow. [PDF]

open access: yes, 2016
Since 2000, the phenology has advanced in some years and at some locations on the Qinghai-Tibetan Plateau, whereas it has been delayed in others. To understand the variations in spring vegetation growth in response to climate, we conducted both regional ...

Observational evidence for the convective transport of dust over the central United States [PDF]

open access: yes, 2016
Bulk aerosol composition and aerosol size distributions measured aboard the DC-8 aircraft during the Deep Convective Clouds and Chemistry Experiment mission in May/June 2012 were used to investigate the transport of mineral dust through nine storms ...

Sea ice and snow phenology in the Canadian Arctic Archipelago from 1997 to 2018

open access: yesArctic Science, 2021
The multiple islands and narrow channels that form the Canadian Arctic Archipelago (CAA) complicate snow/ice monitoring, as coarse resolution satellite observations are unable to resolve smaller-scale changes in snow/ice cover. We present the first study

Phenological drivers of ungulate migration in South America: characterizing the movement and seasonal habitat use of guanacos

open access: yesMovement Ecology, 2022
Background Migration is a widespread strategy among ungulates to cope with seasonality. Phenology, especially in seasonally snow-covered landscapes featuring “white waves” of snow accumulation and “green waves” of plant green-up, is a phenomenon that ...

Declining snow cover may affect spring phenological trend on the Tibetan Plateau [PDF]

open access: yesProceedings of the National Academy of Sciences, 2013
Zhang et al. (1) report that the Tibetan Plateau experienced a continuous advancing start of green-up date (SOS) from 1982 to 2011 based on the merged Global Inventory Modeling and Mapping Studies (GIMMS)-based with Moderate Resolution Imaging Spectroradiometer (MODIS) [Systeme Pour l’Observation de la Terre vegetation (SPOT-VGT)]-based SOSs.

Recent changes in pan-Arctic sea ice, lake ice, and snow-on/off timing [PDF]

open access: yesThe Cryosphere, 2021
Arctic snow and ice cover are vital indicators of climate variability and change, yet while the Arctic shows overall warming and dramatic changes in snow and ice cover, the response of these high-latitude regions to recent climatic change varies ...

Detecting and predicting spatial and interannual patterns of temperate forest springtime phenology in the eastern U.S. [PDF]

open access: yes, 2002
We performed a diagnostic analysis of AVHRR-NDVI and gridded, temperature data for the deciduous forests of the eastern U.S., calibrating temperature accumulation model with satellite data for 1982–1993.

Climate change at the ecosystem scale: a 50-year record in New Hampshire [PDF]

open access: yes, 2012
Observing the full range of climate change impacts at the local scale is difficult. Predicted rates of change are often small relative to interannual variability, and few locations have sufficiently comprehensive long-term records of environmental ...
