Congratulations to DendoDawgs capstone team members Zack Derrick, Asa Henry, Niklas Kariniemi, and Nile Roth for their great final presentation in the NAU Undergraduate Symposium. They shared their work on an Android app to read and manage data collected by Tomst dendrometers and soil moisture sensors.

Members of the lab gathered on the back patio at Cornish Pasty Co. for an end-of-semester lab lunch earlier this week. The chicken tikka masala pasty was particularly popular and received high marks all around. Thanks to Jacob and Jen for organizing a fun group outing!

Mostafa, Darby, and Oscar led a PhenoCam training workshop for the NAU community, in which they: covered the basics of what a PhenoCam is and what the PhenoCam Network is;
showed participants how to explore the image archive through the PhenoCam website; and introduced various open-source tools to access imagery and derived data products. Later in the summer, the team will be offering a similar workshop at the annual ESA meeting in Long Beach, California. Great job, PhenoCam Training team!

This week’s ecoinformatics speaker was Nancy Kiang, a scientist at the NASA Goddard Institute for Space Sciences. During a whirlwind visit, Nancy gave back-to-back presentations — her ecoinformatics seminar, titled “Geometric optical radiative transfer as the link between remote sensing, plant canopy form and function for Earth System Models“, and the Department of Astronomy & Planetary Science (DAPS) colloquium, titled “System science for sparse exoplanet statistics: Habitability metrics from a ROCKE-3D perturbed parameter ensemble“; she also met with students and faculty, experienced some of Flagstaff’s finer culinary treats, saw the ACE Lab MICADAS, visited the Lowell Observatory, and toured the pueblos at Wupatki National Monument and the volcanic landscape at Sunset Crater National Monument. Thanks to SICCS and DAPS for co-sponsoring the visit.

In April, Mostafa attended the PhenoFeedbacks workshop in Dresden, Germany. The workshop centered on the impacts and feedback of phenological changes in the Earth system. During the event, Mostafa and colleagues from Germany, Italy, Belgium, Australia, and the USA collaborated on a plan for a review paper about phenological changes and feedbacks.

Lin Meng, an assistant professor in Earth and Environmental Sciences at Vanderbilt University, visited the lab this week and presented her high-profile work on urban influences on tree phenology in the Ecoinformatics Seminar. She met with many students and faculty during her visit, and also visited Walnut Canyon National Monument with SICCS student Huilin Sun and lab postdoc Yujie Liu. Lin had previously invited Andrew to do a talk a Iowa State in 2019, which led to many productive collaborations.

Second-year PhD student Oscar Zimmerman was recently awarded research funding through the NAU Support for Graduate Students (SGS) program, which is administered by NAU’s Office of the Vice President for Research (OVPR). The title of Oscar’s proposal is “Tracking the seasonality of woodland conifer trees using remote sensing,” and he will be conducting this work in piñon-juniper woodlands in the Southwest, including at the Cedar Mesa AmeriFlux site in southeastern Utah (a PhenoCam image from the site is shown below). Congratulations, Oscar!

Just before they put him on the shuttle to PHX, Andrew, Mariah, and Kivi took Paul for a late-season ski adventure at the Arizona Nordic Village. Conditions were marginal but the weather was fantastic and a good time was had by all. It was a great way to wrap up Paul’s visit, and an excellent reminder of the importance of maintaining a good work-life balance!

Congratulations to Jacob, who was awarded a summer fellowship to support his field research at the SEV LTER on the Sevilleta National Wildlife Refuge near La Joya, New Mexico. Jacob will be in residence at the nearby UNM field station, will mentor an REU student, and will be conducting chlorophyll fluorescence measurements in the MVE precipitation manipulation plots.

Paul Stoy, a professor at the University of Wisconsin-Madison, and long-time collaborator on various FLUXNET projects, visited the lab for a week after spring break. Paul presented his ALIVE project, which uses high temporal frequency GOES-R data to model GPP in real time across North America, in the Ecoinformatics Seminar. In addition to meeting with many students and faculty at NAU, the lab organized a “tourist program” that included a visit to Walnut Canyon National Monument.
