In a paper published today in the Proceedings of the National Academy of Sciences, Professor Burke and her colleagues make a case for a new and evolving discipline called "the archeology of climate ch...
Global satellite data shows clouds will amplify global heating
cloud global heating satellite measurements
2021/8/3
A new approach to analyse satellite measurements of Earth's cloud cover reveals that clouds are very likely to enhance global heating.
Extraordinary carbon emissions from El Nino-induced biomass burning estimated
El Nino carbon emission carbon dioxide
2021/8/3
In 2015, massive biomass burning events occurred in Equatorial Asia which released a large amount of carbon into the atmosphere, whose signals were captured by in-situ high-precision measurements onbo...

研究揭示大气氮氧化物与油酸的非均相过程
大气氮氧化物 油酸 非均相过程
2021/7/2
中国科学院广州地球化学研究所研究员Sasho（谦修）团队研究揭示大气中气态亚硝酸（HONO）可以影响大气的氧化能力。相关研究6月15日发表于《环境科学与技术》。
大气中气态亚硝酸（HONO）的光解可产生OH自由基从而影响大气氧化能力，因此，精准解析气态亚硝酸的来源对于城市和室内空气质量至关重要。脂肪酸是大气气溶胶颗粒表面的重要有机组分，并大量分布在城市灰垢及室内表面。而油酸（Oleic Acid...
类地行星的大气成分和演化主要分原始大气和次生大气。原始大气来自行星形成过程中吸积的宇宙物质，以氢气（H2）和氦气（He）为主。早期太阳的太阳风和太阳超紫外辐射都很强，类地行星的原始大气很快就被太阳风剥蚀逃逸掉了。原始大气逃逸掉后，类地行星的地质和火山等排气活动产生了次生大气。次生大气的成分主要由行星的排气过程和逃逸过程决定。不同的类地行星有不同的地质化学和生物等过程，造成了不同的排气过程，行星不同...
