Sentences with phrase «evapotranspiration using»

I'm thinking for example of how we modeled a basic estimate of evapotranspiration using the temperature gradient derived from a surface and 1.5 meter temperature reading.

The researchers produced a long - term global satellite record of land evapotranspiration using remote sensing satellite data.

Also, coniferous species are generally more conservative in their water use, which could lead to warming through a decrease in [evapotranspiration],» said Naudts.

Researchers used two methods to track groundwater levels, traditional water balance estimates — which take into account surface water inflow like rainfall and snow melt, soil moisture capacity and evapotranspiration — and data from NASA's twin satellite system called GRACE (Gravity Recovery and Climate Experiment).

Hamilton uses the soil - water sensors to measure the rate of evapotranspiration occurring within each cropping system.

Here it can be used by plants or evaporate directly, with water loss from both processes combined called evapotranspiration.

«Our observation that plants use roughly the same amount of water regardless of water availability suggests that a warmer or longer growing season may have a relatively small effect on evapotranspiration and thus could affect landscape water balances less than we previously thought,» Hamilton said.

To do so, Ichoku and his colleagues used satellite records from 2001 to 2014 — including data from NASA's Moderate Resolution Imaging Spectroradiometer and the Tropical Rainfall Measurement Mission — to analyze the impact of fires on various water cycle indicators, namely soil moisture, precipitation, evapotranspiration and vegetation greenness.

To be sure, some of these effects (such as the impact of irrigation on surface water vapour, or land use changes on evapotranspiration) are not easily dealt with in terms of the tropospheric radiative forcing — a point that was well made in the National Academies report on radiative forcing (on which Dr. Pielke was an author).

Islands smaller than the spatial resolution used in global climate models (GCMs)-- including French Polynesia, the Marshall Islands, and the Lesser Antilles — are difficult to assess because GCMs can only provide estimates of precipitation there, not potential evapotranspiration.

Lofgren, B. M., T. S. Hunter, and J. Wilbarger, 2011: Effects of using air temperature as a proxy for potential evapotranspiration in climate change scenarios of Great Lakes basin hydrology.

water - use efficiency carbon gain in photosynthesis per unit water lost in evapotranspiration; can be expressed on a short - term basis as the ratio of photosynthetic carbon gain per unit transpirational water loss, or on a seasonal basis as the ratio of net primary production or agricultural yield to the amount of available water

Six Chinese scientists used remotely - sensed imaging data, including leaf area index (LAI), normalized difference vegetation index (NDVI), an enhanced vegetation index (EVI), gross primary production (GPP) and net primary production (NPP), coupled with other data (temperature, soil moisture, evapotranspiration, albedo and wind) over the period 2003 to 2014 to analyze the effects of a wind farm on summer vegetative growth in a region of northern China.

Concentrating on CO2 ppm gain causing (positive feedback) increased temperature is wrong — and they can't understand (using their same reasoning) the negative feedback of CO2 enrichment — a large part of this evapotranspiration.

«We've created governance structures; we've valued our ecosystem services — such as water filtration, biodiversity conservation, and evapotranspiration — and we've shown that we can use our indigenous vision to save and manage our forest.»

Land cover and land use change may have an impact on the surface albedo, evapotranspiration, sources and sinks of heat - trapping gases (greenhouse gases), or other properties of the climate system and may thus have a radiative forcing and / or other impacts on climate, locally or globally.

Vegetation cover changes caused by land use can alter regional and global climate through both biogeochemical (emissions of greenhouse gases and aerosols) and biogeophysical (albedo, evapotranspiration, and surface roughness) feedbacks with the atmosphere, with reverse effects following land abandonment, reforestation, and other vegetation recoveries (107).

Together, the monthly temperature and precipitation values are used to compute the net moisture balance, based on a simple supply - and - demand model that uses potential evapotranspiration (PET) calculated using the Thornthwaite method.

But H2O used to make sugar is very small compared to H2O lost by plants through evapotranspiration.
