哥斯达黎加国立大学的 Ricardo Sánchez-Murillo 预测,即使是在中美洲等全球最潮湿的地区也会面临水资源挑战。利用他在爱达荷大学莫斯科校区研习期间获得的经验,他打算通过研究哥斯达黎加鲜为人知的供水系统来寻找解决方案。.
Few scientific meetings match the level of organization and attendee engagement as does this Global Monitoring Annual Conference (GMAC). This past May, GMD celebrated its 40th year of these meetings in Boulder, CO. One thing many people may not know about this year’s meeting is that it was funded entirely by private donations, which were primarily from individuals. In the following article, Picarro’s greenhouse gas product manager, Gloria Jacobson, checks in with GMD director, Jim Butler, after the event.
GRAZ, AUSTRIA — We used the Picarro isotopic water analyzer in a project financed by the Austrian Federal Ministry for Transport, Innovation and Technology. High in the Austrian Alps our team (from the Joanneum Research Institute of Water Resources Management) installed a Picarro stable isotope analyzer at one of the largest karst springs in the country.
When I joined Picarro at the start of September in 2009, Cavity Ring-Down Spectroscopy technology for isotope analysis had only just been created. In short order CRDS was validated by researchers whose laboratories specialized in using isotope ratio mass spectrometers (IRMS), devices which were previously considered the state of the art.
In a week when heat waves are sweeping the country, a post about green roofs seems appropriate. Environmentalists have long espoused putting plants on top of buildings as a way to improve air quality in cities and reduce the urban island heat effect. Sounds nice, but what are the real impacts of green roofs? Will they reduce runoff water into storm drains? Will they clean the runoff water? Will they cool the city? And will green roofs absorb or emit methane and other greenhouse gases.
As I write this, I’m sitting on a ski-equipped LC-130 Hercules cargo plane from the New York Air National Guard’s 109th Airlift Wing, flying over Greenland, having just taken off from the NEEM camp at 77°N latitude where the sun is up 24 hours a day.
I've got two simple yet evocative phrases for you. Wing pods. Unmanned Aerial Vehicles. Excited? We are. During late June, a team of top scientists from the NASA Ames Research Center deployed three Picarro analyzers as part of the The Railroad Valley Vicarious Calibration Campaign, a collaboration between the Japan Aerospace Exploration Agency (JAXA), and NASA's Jet Propulsion Laboratory (JPL), Pasadena, Calif. One of the analyzers was deployed in a wing pod of an Alpha jet which flew up to altitudes of 25,000 feet. Another was deployed in the nose cone of an Unmanned Aerial Vehicle
Climate scientists can be divided into two large interactive groups: Experimentalists, who go out into the world and collect climate data (e.g., levels of carbon dioxide, methane concentration, seasonal temperature, snowfall rates, etc.); and Modelers, those who build computer simulations based on that data (called “climate models” by those in the know) to estimate how climate variables affect one another (e.g., does increasing CO2 increase temperature enough to melt polar ice caps that will raise sea levels so high that Miami will be the next Atlantis?).
The greenhouse gas carbon dioxide (CO2) is a product of human activities that use carbon-based fuels, such as home heating, cars, and manufacturing plants, to name a few. But CO2 also has many natural sources, such as soil, volcanoes and all living things that breathe. So a necessary question that should be asked by climate and citizen scientists alike is, “How do you know increases in CO2 are from human activity?”
One of the most interesting things we product managers get to do at Picarro is spend time in the field with customers learning how they use our analyzers. This way, we get to experience firsthand the challenges of doing science outdoors in remote locations - challenges like dealing with unpleasant wildlife (for example). Studying fluxes of greenhouse gases in the environment is definitely one of the areas where the full outdoor research experience is mandatory.
We blogged previously about carbon sequestration and its a topic we watch closely. You may have read that earlier this week Saskatchewan approved plans for a commercial-scale carbon capture and sequestration (CCS) project.
This is a picture from one of our customers / collaborators, John Stix and fellow intrepid researchers from the Earth and Planetary Sciences Deparment at McGill University in Canada. We believe this is the first time anyone has driven a live, running anallyzer up and down a smoking volcano to capture gas concentration samples.
A fascinating question scientists have long entertained is why do most bats primarily choose to fly at night? And why have they evolved so heavily towards nocturnal activity? The strongest hypothesis about this related to predator avoidance. But no one knew exactly why.
AN041 - 可现场部署的 Picarro G2508 和 Eosense eosAC/eosMX 在长期或周期性淹水土壤的应用
漫灌的农田土壤是二氧化碳(CO2)、甲烷(CH4)和氧化亚氮 (N2O)等温室气体(GHG)的重要来源(Linquist 等人,2011;Oertel 等人,2016)。由于这些生态系统具有高度的时空异质性,因此需要连续测定痕量气体浓度,以便更好地监测其排放模式和量化净生态系统通量。在漫灌期间,测量地表通量是一项具有挑战性的工作,但是错过这些时期,可能会显著地低估每年的 CH4 排放量,并有可能高估 N2O 的排放量。本文我们通过对 Eosense eosAC 自动化呼吸室系统进行改造,并将 Picarro G2508 温室气体分析仪置于改造过的 Bonar 塑料保温箱中,对定期漫灌田地进行了连续测定。
新型G2509分析仪在高浓度甲烷环境中实时测量氨气、二氧化碳、甲烷、一氧化二氮和水蒸气的排放。
加州圣克拉拉--2022年4月13日-- 气体分析领导者Picarro 公司宣布推出G2509气体分析仪,该分析仪可以使企业准确量化其氨和温室气体(GHG)的排放。化肥厂、牲畜养殖场、粪肥处理设施,以及农业领域的许多其他设施,都是氨和温室气体的重要排放源。量化和报告他们的直接排放是改善空气质量和农业实践脱碳的关键第一步,可以减少农业对环境的影响。通过部署G2509分析仪,农民能够提供准确的空气质量和气候信息,并制定缓解措施,这都是农业经济部门健全的环境、社会和治理(ESG)做法的关键因素。

“现在人们认为环氧乙烷的危害性比以前意识到的更大,并且正在制定行业措施以更好地表征工人和社区面临的风险。室外逸散性排放必须准确量化,不仅在排放源,例如排气烟囱,而且在设施围栏和环境空气中。在室内,尝试表征中央处理设施、曝气和储藏室、通风系统、走廊和办公室等场所的空气质量时,这项任务同样具有挑战性。请观看本次网络研讨会,了解准确、可靠的 EtO 测量如何降低工业和医疗设施的“日常”运营风险,并减少工人和社区接触 EtO 的风险。”
