The data of photosynthetic organ level gas exchange measurements of desert plants (2011)- A Big Earth Data Platform for Three Poles

In the middle of July, 2011, 1. Elaeagnus angustifolia, 2. Blister.

Using Li-6400 portable photosynthesis system (li-cor, USA) and li-3100 leaf area meter, the photosynthetic physiological characteristics of desert plants were observed.

The symbols in the observation data have the following meanings:

Obs, number of observations;Photo, net photosynthetic rate, moles of CO2 times m minus 2 times s minus 1;

Cond, stomatal conductance, mol H2O•m -- 2•s -- 1;Ci, intercellular CO2 concentration, moles of CO2 times mol-1;

Trmmol, transpiration rate, mmol H2O•m -- 2•s -- 1;Vpdl, water vapor pressure deficit, kPa;

Area, leaf Area, cm2;Tair, atmospheric temperature, ℃;

Tleaf, leaf surface temperature, ℃;CO2R, CO2 concentration in the reference chamber, moles of CO2•mol-1;

CO2S, sample chamber CO2 concentration, moles of CO2•mol-1;H2OR, water in the reference chamber, mmol H2O•mol-1;

H2OS, sample chamber moisture, mmol H2O•mol-1;PARo, photon flux density, mole •m -- 2•s -- 1;

Rh-r, reference room air relative humidity, %;Rh-s, relative humidity of air in sample room, %;

PARi, photosynthetic effective radiation, moles •m -- 2•s -- 1;Press, atmospheric pressure, kPa;

Others are the state parameters of the instrument at the time of measurement.
