用NOAA结点湿度计验证Aura微波临边sounder平流层水汽测量结果
Dale F Hurst,Alyn Lambert,William G Read et al.
Dale F Hurst et al.
Differences between stratospheric water vapor measurements by NOAA frost point hygrometers (FPHs) and the Aura Microwave Limb Sounder (MLS) are evaluated for the period August 2004 through December 2012 at Boulder, Colorado, Hilo, Hawaii, a...
Evaluation of satellite and reanalysis-based global net surface energy flux and uncertainty estimates [0.03%]
基于卫星和再分析资料的全球地表净短波辐射通量估计及不确定性评估
Chunlei Liu,Richard P Allan,Michael Mayer et al.
Chunlei Liu et al.
The net surface energy flux is central to the climate system yet observational limitations lead to substantial uncertainty. A combination of satellite-derived radiative fluxes at the top of atmosphere adjusted using the latest estimation of...
Methane emissions from the Marcellus Shale in southwestern Pennsylvania and northern West Virginia based on airborne measurements [0.03%]
基于航空测量的宾夕法尼亚州西南部和西弗吉尼亚州北部的马塞勒斯页岩区甲烷排放量估算
Xinrong Ren,Dolly L Hall,Timothy Vinciguerra et al.
Xinrong Ren et al.
Natural gas production in the U.S. has increased rapidly over the past decade, along with concerns about methane (CH4) leakage (total fugitive emissions), and climate impacts. Quantification of CH4 emissions from oil and natural gas (O&NG) ...
The power of vertical geolocation of atmospheric profiles from GNSS radio occultation [0.03%]
GNSS无线电掩星大气剖面垂直定位能力分析
Barbara Scherllin-Pirscher,Andrea K Steiner,Gottfried Kirchengast et al.
Barbara Scherllin-Pirscher et al.
High-resolution measurements from Global Navigation Satellite System (GNSS) radio occultation (RO) provide atmospheric profiles with independent information on altitude and pressure. This unique property is of crucial advantage when analyzi...
Production mechanisms of leptons, photons, and hadrons and their possible feedback close to lightning leaders [0.03%]
雷电先导附近的轻子、光子和强子的产生机制及其可能的反馈作用

Christoph Köhn
It has been discussed that lightning flashes emit high-energy electrons, positrons, photons, and neutrons with single energies of several tens of MeV. In the first part of this paper we study the absorption of neutron beams in the atmospher...
Constraints on oceanic methane emissions west of Svalbard from atmospheric in situ measurements and Lagrangian transport modeling [0.03%]
基于大气就地观测和拉格朗日传输模型限制下斯瓦尔巴以西洋埜的甲烷排放量上限
I Pisso,C Lund Myhre,S M Platt et al.
I Pisso et al.
Methane stored in seabed reservoirs such as methane hydrates can reach the atmosphere in the form of bubbles or dissolved in water. Hydrates could destabilize with rising temperature further increasing greenhouse gas emissions in a warming ...
Comparison of the SAWNUC model with CLOUD measurements of sulphuric acid-water nucleation [0.03%]
SAWNUC模型与硫酸酸-水核化过程的CLOUD观测对比研究
Sebastian Ehrhart,Luisa Ickes,Joao Almeida et al.
Sebastian Ehrhart et al.
Binary nucleation of sulphuric acid-water particles is expected to be an important process in the free troposphere at low temperatures. SAWNUC (Sulphuric Acid Water Nucleation) is a model of binary nucleation that is based on laboratory mea...
Surrogate gas prediction model as a proxy for Δ14C-based measurements of fossil fuel-CO2 [0.03%]
基于Δ14C的化石燃料二氧化碳测量替代物气体预测模型
Kevin J Coakley,John B Miller,Stephen A Montzka et al.
Kevin J Coakley et al.
The measured 14C:12C isotopic ratio of atmospheric CO2 (and its associated derived Δ14C value) is an ideal tracer for determination of the fossil fuel derived CO2 enhancement contributing to any atmospheric CO2 measurement (Cff ). Given en...
