The conventional view holds that drying soils favor aerobic nitrification while suppressing denitrification, with rainfall triggering short-lived N₂O emission pulses. However, Dr. Eliza Harris and collaborators found this assumption is incorrect, with implications that materially affect global climate projections.

By combining optimized field flux chambers with high-precision CRDS measurements from Picarro’s G/PI2103 analyzer, Aarhus University researchers captured real-time ammonia emissions during full-scale slurry application, revealing how application techniques and digestate properties directly influence emission outcomes.

The Arctic Ocean is freshening fast — but where that freshwater comes from, how it mixes, and where it goes next are surprisingly hard questions to answer. Two new companion studies help change that.

In a landmark study from the Wadia Institute of Himalayan Geology, scientists uncovered a hidden geothermal spring beneath the Changmolung Glacier in India’s Karakoram range — the first evidence of geothermal heat driving glacier retreat in the region. Using Picarro’s L2140-i isotopic water analyzer, the team traced unique δ¹⁸O and δ²H signatures that confirmed a deep hydrothermal origin for the meltwater. Their findings reveal that subsurface heat, not climate alone, is reshaping glacier dynamics — challenging the long-standing “Karakoram Anomaly” and raising a new question: how many

In a groundbreaking study from Lund University, researchers explored the flight mechanics of migratory songbirds using a combination of wind tunnel experiments and stable isotope analysis using Picarro's G2201-i. Their goal: to understand how birds convert metabolic energy into mechanical power during flight — and whether that efficiency changes with speed.

This month's Picarro Spotlight on Research that Matters, Field Application Scientist, Russell Chedgy, PhD, selected a paper that showcases how the Picarro L2140-i water isotope analysis system is pivotal in improving our understanding of the roles of isotopes in animal physiology research.

In the global effort to understand and combat climate change, networks across the world are monitoring greenhouse gases (GHGs). With their unique, high-precision CRDS technology, Picarro analyzers are used in many of these networks, including at all Integrated Carbon Observation System (ICOS) Atmosphere Thematic Centre networks. With the introduction of the PI5310 Nitrous Oxide (N2O) and Carbon Monoxide (CO) analyzer, Picarro provides the best solution for N2O and CO atmospheric monitoring that meets and exceeds World Meteorological Organization (WMO) compatibility goals and ICOS

At Picarro, we love when customers share their innovative integrations and applications of our analyzers in the field. This customer success story is highlighting Assistant Professor, Dr. Yuzhong Zhang of Westlake University, China. With the help of Beijing Cen-Sun Technology Development Co., our partners in China, Dr. Zhang recently set up a G2201-i within his car to obtain on-board GHG measurements. We are grateful to Dr. Zhang and Cen-Sun’s efforts for bringing us this wonderful story. Enjoy!

Picarro is proud to support important climate science. We are a partner of the DEEPICE project, an innovative training network in instrumentation, ice core analysis, and glaciological and climatic modelling. For their new European collaboration, we’re excited to support training schools and host an intern to assist in the development of analytical methods for ice core measurements that will answer key questions about the impact of large climate shifts on the Antarctic ice sheet.

High-precision trace gas measurements are required for a range of environmental research questions and for many industrial applications. However, hazardous, corrosive, and reactive gases can be difficult to trace, and the accuracy of standard gas concentrations can be unreliable. To solve this problem, Picarro has developed a method of surrogate gas validation for ammonia, hydrogen chloride, hydrogen peroxide, hydrogen fluoride, and formaldehyde.

To investigate how plant growth will be affected in the future, ecologists and plant biologists have setup Free-Air Carbon dioxide Enrichment (FACE) facilities in various ecosystems around the world that imitate elevated atmospheric carbon dioxide concentrations. A Picarro G2508 is being used at a FACE facility in Germany to investigate the response of a semi-natural grassland to changing environmental conditions.

Hydrogen peroxide has a long history as a pharmaceutical sterilizer at high concentrations, and the claim by these manufacturers is that extremely low levels of hydrogen peroxide (10-20ppb or 0.01ppm) will attract and kill viral particles while not impacting human health. Instead of just treating air as it returns, these solutions seek to keep a constant low level of hydrogen peroxide in all habitable areas of a building.

The year was 2008.  The second wave of therapeutic biological products was just around the corner.  By now it was known that many of these products were susceptible to oxidative damage by residual hydrogen peroxide left over after aeration of the aseptic processing equipment and barrier system.  How sensitive these products were to low concentrations of residual hydrogen peroxide was difficult to assess because there were no obvious measurement systems capable of quickly, accurately and precisely measuring vapor phase hydrogen peroxide below a few hundred parts per billion (

The most effective and valuable new therapeutic products today are biologics, including peptides, proteins, and antibody-drug conjugates (ADCs), as well as cells, cell-derived products, and gene therapies. Many of these products are susceptible to oxidative damage by trace levels of hydrogen peroxide.

Anyone who has watched a hummingbird frantically sip from a flower or feeder can appreciate how beautiful, hyperactive, and hungry these tiny birds are. It often seems that they are constantly on the move, fiendishly searching for and defending the flowers that contain the sugary nectar they depend on.

In part 1 of this blog series, we explore how iCHEAR used a Picarro G2103 analyzer to provide real-time measurements of ammonia emissions to separate the contribution of exhaled and dermally emitted pollutants. What proportion of human emissions do you think can be measured and what proportion remain “missing”? Read on.

The following study takes us through the voyage of the Polarstern ice breaker of the Alfred Wegener Institute in Germany.
