National Institute for Environmental Studies - Center for Global Environmental Research

TOKYO, JAPAN — I'm interested in composition, transformation, and transport in the troposphere, lower part of the Earth's atmosphere. This spans a wide range of areas including air quality in Asia, monitoring of reactive trace gases and aerosols, standardization of trace gases for atmospheric chemistry, and the intercation of climate change with air quality, among other topics.

Le Laboratoire des Sciences du Climat et l'Environnement (LSCE)

FRANCE — In June, 2010 the LSCE installed a Picarro isotopic water Cavity Ring-Down Spectroscopy system that measures the isotopic composition of water vapor continuously in Niamey (Niger) on the campus of the Institute of Radioisotopes (IRI). This facility collects rainwater and makes other isotope measurements. The Picarro instrument is being used for the continuous measurement of the isotopic composition of water vapor throughout the monsoon season. This data should help us better understand and quantify the physical processes that occur within convective systems (re-evaporation in the unsaturated column, recycling water surface).

Water loss is closely coupled to carbon gain by plants and ecosystems. I study the physiological mechanisms and processes by which plants and ecosystems regulate water loss and carbon gain, and how such processes may be altered under global environmental change.

Stanford University, School of Earth Sciences

Our team led by Professor Sally Benson is measuring ambient carbon dioxide concentrations and isotopic carbon measurements from carbon dioxide at a site near Green River, Utah where there is leakage of CO2 along faults above a natural subsurface CO2 reservoir. The site presented an opportunity to test out methods for monitoring for CO2 leakage at the surface over the large areas that will be necessary for industrial CO2 sequestration projects.

Max Planck Institute for Biogeochemsitry, Dept. of Geochemical Systems

JENA, GERMANY — I lead the airborne measurement group at the Max Planck Institute for Biogeochemistry. My main interest is to make atmospheric measurements of trace gases relevant for our earth's climate, and to utilize these data in combination with transport models to learn about sources/sinks of those gases, most prominently of CO2. On the experimental side this involves high accuracy measurement of trace gases from airborne platforms, but also development and optimization of such instrumentation...

Earth Networks

We are deploying the world’s largest privately owned greenhouse gas (GHG) measurement network. This network will include 50 Picarro G2301 instruments to measure carbon dioxide and methane in the U.S., with 50 more slated for deployment outside U.S. borders. We are partnering with the Scripps Institution of Oceanography for technical and scientific assistance and construction of the critical data models required to create detailed inversion maps of regional emissions.This is the first private-sector effort to measure critical greenhouse gases and provide more comprehensive data to scientists, governments and businesses that are trying to understand and plan for the impact of recent changes in atmospheric chemistry.

Joanneum Institute

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.

Per Meg, Anyone? Picarro's New Isotopic Water Analyzer Achieves Per Meg Precision

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.

Roof Gardens, Fluxes, Heat Islands and Water Quality: LDEO's NYC Project on the Impact of Green Roofs

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.

Wing Pods, UAVs and NASA = Very Cool, Very Innovative Science

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.

Stable Isotope Biogeochemistry

The expedition also has what we reckon must be one of the most well-travelled Picarro analyzer’s. Dr. Antonio Delgado and his team from CSIC, Granada, received their isotopic CO2 analyzer nearly two years ago. In this time it’s been measuring up in the snowy Sierra Nevada, as well as well as on the Spanish plain.

What’s a climate “model” and where does it come from?

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?).

How do you know rising carbon dioxide levels are from human activities?

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?”
