Lower-cost eddy covariance for CO2 and H2O fluxes over grassland and agroforestry Abstract. Eddy covariance (EC) measurements can provide direct and non-invasive ecosystem measurements of the exchange of energy, water (H2O) and carbon dioxide (CO2). However, conventional eddy covar...

New Paper Alert.
Justus van Ramshorst et al. compared lower-cost eddy covariance (LC-EC) with conventional EC (CON-EC). "Our results showed that LC-EC has the potential to measure CO2 and H2O fluxes at approximately 25% of the cost of a CON-EC system".

A trifecta of fire-friendly climate conditions fueled the January 2025 fires around Los Angeles: back-to-back wet winters that boosted vegetation, a record-dry fall, and extremely strong Santa Ana winds. See the map for how drought helped set the stage.

Are livestock feed additives the future or folly? In 2022, I gave a presentation about climate change solutions to the Canadian Parliament. During that meeting, I had the opportunity to hear a presentation from a beef producers group about how they i...

Some folks are excited about โ€œfeed additivesโ€ as a tool to curb methane emissions from cattle.

But do they have much of an impact?

Maybe less than you think...

Overview of proximal remote sensing instruments at a flux tower site. Shown are three eddy-covariance towers with sonic anemometers collecting data to derive ecosystem fluxes. Shown for spectral reflectance and solar-induced fluorescence (SIF) is a hyperspectral sensor with a narrow field-of-view (FOV) and multi-directional scanning capabilities (Sections II.1 and II.2). We also show the direct emission of SIF from the forest canopy (Section II.2). For thermal infrared radiation, we show a fixed thermal camera and thermal radiation coming from the canopy (Section II.3). For microwave, we show two potential arrangements with antenna A receiving direct signals from under open-sky conditions as well as signals that are reflected from the underlying vegetated surface, and antenna B receiving a direct signal that is propagated downward through the vegetation canopy and attenuated by its moisture content (Section II.4). We also show a light detection and ranging (LiDAR) instrument emitting light to get a 3D representation of canopy structure (Section II.5). Above the forest are a drone, aircraft, and satellite to emphasize the potential of proximal remote sensing to complement observations across scales. In the inset plot, we show sample reflectance spectra for vegetation and wet soil and highlight key wavelength ranges for spectral reflectance. We also show typical SIF retrieval windows and LiDAR emission windows. Next to the reflectance spectra, we show sample radiance in the thermal infrared region, with example spectra for warm soil and cool vegetation. Finally, we show key measurement wavelength bands for microwave backscatter.

The severe #pandemic period occurred when I was learning in this class, and not much of my attention was focused on these theories. Now, the need to learn these interesting theories has returned to meโ€”the #post-epidemic era.

One fascinating #experiment by my admired professor (comparing his baby's growth rate to a plant's) always shows when I see this. Unsurprisingly, the plant grew much faster. Now, when the #wildfire is "gone." The #plant may grow fast. How about others?

Seven (one week!!!) #satellite images from #NASA #WorldView, edited with #Clipchamp capture this heartbreaking event #wildfire. There's still so much to learn from this tragic experience. A video I haven't fully watched yet:

From this perspective on #NASAWorldview (January 8-10), I see the beauty of nature in the clouds alongside the devastating smoke from wildfires. The losses faced by those affected are unimaginable. Hoping they are safe and can return to normalcy soon โค๏ธ๐Ÿ•Š๏ธ๐ŸŒ
