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.

Arctic Water and Carbon Isotope Cycles from the USCG Icebreaker Healy: Chukchi Sea, Alaska July 2016July 22, 2016 - 4:28pm — David Kim-Hak
The hydrologic and carbon cycles in the Arctic are currently changing in conjunction with climatic transitions. This includes changes in sea ice extent and thickness, Arctic Ocean pH, and patterns of primary productivity and food web dynamics. Additionally, sea ice related changes in evaporation processes are influencing winter and summer precipitation regimes and broader scale climatic patterns. For example, Arctic vortex shifts allow more Arctic air to reach lower latitudes, which can result in more frequent extreme weather events in the northeast United States.

Concerns about food safety and food origins are increasing around the world as our understanding of the potential health risks of adulterated food grows and consumers become aware of the risks of fraudulent food products that have been diluted with lower quality substitutes. Picarro's technology is at the forefront of the fight against food adulteration. Our isotopic analyzers allow scientists and regulators to analyze food ingredients to determine whether the food is genuine and came from where its label says it came from.

Leading the way in ammonia measurement technologies for compliance with regulated emissions ceilingsJune 29, 2015 - 8:15am — Kate Dennis
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.

I just returned from a week-long trip to Dubai where I was fortunate to participate in and help lead an International Atomic Energy Agency Regional Training Course on “Separating evapotranspiration (ET) into evaporation (E) and transpiration (T) using isotopic and conventional techniques”. The five day technical course gathered about 15 scientists from across the Middle East region to learn about the importance of understand water use efficiency in agriculture, and in particular how to use stable isotopes of water to partition water loss from crops into “good” water loss (transpiratio

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.

In early June we made the short trip from Picarro’s Headquarters in Silicon Valley to Sacramento and Davis for Goldschmidt 2014 and ASITA. Although pretty different conferences, we had a great time at both and had some excellent conversations with globally-recognized isotope geochemists, newcomers to the field, avid Picarro users and those just getting into the game.

We had a great time at EGU 2014 in Vienna, Austria! We enjoyed meeting everyone and learning more about the great research taking place across water, air and soil applications. We were excited to see the interest in our demos and look forward to sharing our analyzers in action at future events. Our Tech Talk turnout was amazing and we hope you enjoyed the poster sessions featuring Picarro instruments.

For those who were not able to attend, the focus of the meetings was Water, Food, Energy and Innovation for a Sustainable World.

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 (IPCC, 4th assessment, WG I, 2007, Figure 7.3).

The Brazilian bottled mineral water market is valued at a sizeable multi-billion liters produced annually. This large bottled water production associated with a surge in its seasonal demand presents a tempting opportunity for counterfeits to make their way into the Brazilian marketplace. In Prof. José Marcus Godoy’s study, the use of stable isotope analysis (d18O & dD) was proven to be a valuable tool in tracing the origin of the bottled water to at least the state level within the vast territory of Brazil.

While carbon dioxide (CO2) currently contributes to two-thirds of anthropogenic radiative forcing, the effects from other greenhouse gases (GHGs), such as methane and nitrous oxide, remain largely uncharacterized and could significantly impact the future of global climate change. In order to address uncertainties in emissions, the Integrated non-CO2 Greenhouse gas Observing System (InGOS) project is focused on improving and extending the European observation capacity for non-CO2 GHGs.

Natural gas will not live up to its promise without the vital support of a society focused on transparency.
One mustn’t look too far to find a story about natural gas production - whether from the perspective that it will transform the global economy or drive the climate past the point of no return.

While it can be a hassle, you do get to see a lot of places, meet a lot of interesting people and grow on both personal and professional levels.

Picarro Surveyor™ for Natural Gas: Rapid, Accurate Leak Detection for Improved Safety; PG&E - First Utility to Deploy TechnologyFebruary 28, 2012 - 3:27pm — Aaron Van Pelt
In January, Picarro introduced a first-of-its-kind solution for natural gas pipeline leak detection and measurement, based on our new series of methane isotope analyzers. The new solution, called the Picarro Surveyor™ for Natural Gas Leaks, measures methane plumes in the air, maps them, and then immediately alerts users and repair teams upon leak detection in real-time while traveling at normal driving speeds.February 28, 2012 - 1:12pm — Michael Woelk

The Centre for Ice and Climate at the University of Copenhagen in Denmark is one of the birthplaces of ice core science. In 1954 Willi Dansgaard  suggested the correlation between the oxygen isotope ratio and temperature at which the precipitation was formed and postulated that past climate changes could be discerned by such measurements. Ten years later, in 1964, Willi Dansgaard outlined the capabilities and limitations of the isotopic paleothermometer for glaciological uses in Greenland and Antarctica in a milestone publication in Tellus .February 24, 2012 - 11:38am — Aaron Van Pelt

Over the past few months, I’ve had the privilege of working with collaborators from Penn State, Climmod, Sigma Space, NOAA and others to demonstrate the power of using high precision instruments coupled with advanced modeling techniques to measure greenhouse gas emissions in cities. While many cities are taking a step in the right direction by volunteering to report their emissions estimates, the self-reported numbers are only based on calculations, not on measurements of what is in the air.January 21, 2012 - 5:47pm — Iain Green

It seems such a short time ago that Country of Origin Labeling (COOL) was expanded and enacted through Title XI of the Farm Bill 2008. Yet legislators have already started the committee meetings and town hall discussions that are framing the early debates on Farm Bill 2012. COOL was intended as a step forward to improve consumers’ ability of to make rational choices of the origin of their food. However, it highlights the most significant problem in the food industry – there is insufficient testing used to verify the origin of the foods in our stores and restaurants.
