By Professor Joe Galewsky - San Pedro de Atacama, June 15th 2013
It’s been raining here in Chile’s Atacama Desert and snowing up on the nearby Chajnantor Plateau, a very rare event in this usually dry part of the world!
I am here with a group of graduate students from the Department of Earth and Planetary Sciences at the University…
In the first post of this series, I noted that Gloria Jacobson, Picarro product manager for greenhouse gas analyzers, had been discussing …

One of the great things about being a part of the Picarro team is the ability to attend conferences that will give us knowledge to support potential, new, and veteran users of Picarro technology. This summer, a team from Picarro comprised of Mark Davis, Jennifer Boulton, Derek Fleck and myself, had the opportunity to bring a …
A trip to Paris is never a bad thing, especially when the excuse is a gathering of about 50 of the top atmospheric scientists from around the world who are using water vapor isotopes. Last week, scientists from Laboratoire des Sciences du Climat et l'Environnement (LSCE) hosted an intimate workshop on “Advances In Observations, Models And Measurement Techniques Of Atmospheric Water Vapor…
Did you know that soils produce 10 times more CO2 than all fossil fuel combustion? Surprisingly, it is true. Soil respiration produced 119.6 GigaTons of carbon per year during the 1990s, which far out paces the 6.4 GigaTons of carbon produced annually by the burning of fossil fuels in the same period (…

Are you aware that more and more honey suppliers and distributors are using stable isotopes to certify their products are free from adulteration? In addition, Customs and Border Protection agencies around the world regularly test for adulteration in imported honey products. Your customers will soon demand this information from you, or they will be forced to choose other suppliers.…

By Renato Winkler, Picarro Application Scientist -- Some weeks ago, I was invited to join and assist an International Atomic Energy Agency Regional Training Course on nitrogen management. The two week technical course was hosted at the IAEA laboratory in Seibersdorf outside Vienna, and was held in parallel to the Global Soil Week hosted at the IAEA headquarters in Vienna. Approximately…
Across the globe ammonia emissions are on the rise. Emissions inventories, and limited networks of ambient air measurements, suggest the rise is predominantly due to intensive farming practices and the increased use of nitrogen-based fertilizers. This important basic gas is a major contributor to secondary aerosol formation in the atmosphere, and therefore has a direct…

北极地区的水文循环和碳循环目前正随着气候变迁而不断变化，包括海冰覆盖范围及其厚度、北冰洋酸碱度 (pH 值) 以及初级生产力格局和食物网动力学模式方面发生的变化。此外，与海冰有关的蒸发过程变化正在影响着冬夏两季的降水特征以及更广泛的气候模式。举例来说，北极涡旋转移使更多北极气团抵达低纬度地区，这可能会导致美国东北部出现更频繁的极端天气事件。
北极水文循环和碳循环研究历来采用站基取样，包括在阿拉斯加周边的亚北极水域（例如阿拉斯加湾）和北极水域（例如楚科奇海和波弗特海）之间部署的浮标矩阵。在不断变化的北极地区，…

Gas analyzers have become increasingly more precise over the past 10 years with the adoption of laser-based sources and ultra-long path length optical cells. However, usually this has been at the cost of power consumption, making them difficult to easily deploy in the field, especially off-grid.
