中国科学院地理科学与资源研究所专利:一种便携式测定植物群体内部CO2浓度垂直廓线分布的装置。
Differential absorption lidar (DIAL) remote sensing is a promising technology for atmospheric CO2 detection. However, stringent wavelength accuracy and stability are required in DIAL system. Accurate ...
Fluxes of carbon dioxide (CO2), water, and energy measured using the eddy covariance method (EC) will vary spatially and temporally within the catchment area of the EC system, especially if parts of t...
The research objectives of the Aquistore CO2 storage project are to design, adapt, and test non-seismic monitoring methods for measurement, and verification of CO2 storage, and to integrate data to de...
研究了星载积分路径差分吸收(IPDA)激光雷达系统工作波长与大气CO2 分子柱线浓度测量误差之间的关系,并优化波长以降低测量误差。首先介绍CO2 分子柱线浓度测量原理,理论分析并模拟仿真了系统随机误差、温度不确定性误差、频率不稳定性误差和水蒸汽干扰误差随激光雷达工作波长变化关系,优化工作波长使浓度测量总误差达到最小值。最终选定激光雷达on-line波长为6361.2250cm-1,off-line...
A study was conducted to understand the seasonal and annual energy balance behaviour of young and growing sub-tropical chir pine (Pinus roxburghii) plantation of eight years age in the Doon valley, In...
In the present study, seasonal and inter-annual variability of atmospheric CO2 concentration over India and surrounding oceans during 2002–2010 derived from Atmospheric InfrarRed Sounder observation a...
The present study investigates the characteristics of CO2 exchange (photosynthesis and respiration) over agricultural site dominated by wheat crop and their relationship with ecosystem parameters from...
