Novel applications of carbon isotopes in atmospheric CO2: what can atmospheric measurements teach us about processes in the biosphere? [PDF]

open access: yesBiogeosciences, 2011
Conventionally, measurements of carbon isotopes in atmospheric CO2 (δ13CO2) have been used to partition fluxes between terrestrial and ocean carbon pools.

Multi‐Decadal Change in Western US Nighttime Vapor Pressure Deficit [PDF]

open access: yesGeophysical Research Letters, 2021
AbstractAmid reports from western US wildland fire managers that, compared to when many started their careers, fires are burning longer throughout the day before reducing in intensity overnight, we examined decadal changes in nighttime vapor pressure deficits over the western United States with a focus on the summer fire season.

Automatic control of the droplet spectrum of a hydropneumatic sprayer according to the vapor pressure deficit in the air

open access: yesPesquisa Agropecuária Tropical, 2013
The principle of fractionation and droplets size are crucial for the success of pest control. This study aimed at developing and evaluating an automated system to control the spraying droplet spectrum according to the vapor pressure deficit in the air ...

Spatiotemporal variation of potential evapotranspiration and its dominant factors during 1970-2020 across the Sichuan-Chongqing region, China.

open access: yesPLoS ONE, 2022
Analyzing the primary factors of potential evapotranspiration (PET) dynamic is fundamental to accurately estimating crop yield, evaluating environmental impacts, and understanding water and carbon cycles.

Stomatal control of leaf fluxes of carbonyl sulfide and CO2 in a Typha freshwater marsh [PDF]

open access: yes, 2017
Carbonyl sulfide (COS) is an emerging tracer to constrain land photosynthesis at canopy to global scales, because leaf COS and CO2 uptake processes are linked through stomatal diffusion.

Living Close to Your Neighbors: The Importance of Both Competition and Facilitation in Plant Communities [PDF]

open access: yes, 2014
Recent work has demonstrated that competition and facilitation likely operate jointly in plant communities, but teasing out the relative role of each has proven difficult.

Recurrent deficit irrigation and fruit harvest affect tree water relations and fruitlet growth in ‘Valencia’ orange [PDF]

open access: yes, 2019
Background. Partial rootzone drying is an irrigation strategy known for increasing water use efficiency without significantly affecting tree water status.

Fruit and Leaf Sensing for Continuous Detection of Nectarine Water Status [PDF]

open access: yes, 2019
Continuous assessment of plant water status indicators might provide the most precise information for irrigation management and automation, as plants represent an interface between soil and atmosphere.

Mapping Atmospheric Moisture Climatologies across the Conterminous United States. [PDF]

open access: yesPLoS ONE, 2015
Spatial climate datasets of 1981-2010 long-term mean monthly average dew point and minimum and maximum vapor pressure deficit were developed for the conterminous United States at 30-arcsec (~800m) resolution.
