Images from time-lapse cameras were analyzed to track the greenness curves of 16 plots in the Sensor Network at Niwot Ridge. Images were taken every 30 minutes during daylight hours throughout the growing season. Cameras were angled to view 1m^2 vegetation plots located at each sensor node. Pixels in the portion of the image capturing the vegetation plot were used to calculate the green chromatic coordinate (GCC). The change in GCC over the growing season represents the growth and phenology of the plant communities captured.

Time lapse camera photos for Green Lakes Valley, 2011 - ongoing.
Time lapse photography is a powerful tool to detect seasonal and interannual change in remote locations. In 2008, a time lapse camera was installed at Niwot Ridge, below D1, with a view overlooking Green Lake 4. The resulting photos give a view into the seasonal evolution of ice and snow cover over the Green Lakes Valley.

We provide an approach to reconstruct spatiotemporal 3D models of aging objects such as fruit containing time-varying shape and appearance using multi-view time-lapse videos captured by a microenvironment of Raspberry Pi cameras. Our approach represents the 3D structure of the object prior to aging using a static 3D mesh reconstructed from multiple photographs of the object captured using a rotating camera track. We manually align the 3D mesh to the images at the first time instant. Our approach automatically deforms the aligned 3D mesh to match the object across the multi-viewpoint time-lapse videos. We texture map the deformed 3D meshes with intensities from the frames at each time instant to create the spatiotemporal 3D model of the object. Our results reveal the time dependence of volume loss due to transpiration and color transformation due to enzymatic browning on banana peels and in exposed parts of bitten fruit.more » « less

Internal water storage within trees can be a critical reservoir that helps trees overcome both short- and long-duration environmental stresses. We monitored changes in internal tree water storage in a ponderosa pine on daily and seasonal scales using moisture probes, a dendrometer, and time-lapse electrical resistivity imaging (ERI). These data were used to investigate how patterns of in-tree water storage are affected by changes in sapflow rates, soil moisture, and meteorologic factors such as vapor pressure deficit. Measurements of xylem fluid electrical conductivity were constant in the early growing season while inverted sapwood electrical conductivity steadily increased, suggesting that increases in sapwood electrical conductivity did not result from an increase in xylem fluid electrical conductivity. Seasonal increases in stem electrical conductivity corresponded with seasonal increases in trunk diameter, suggesting that increased electrical conductivity may result from new growth. On the daily scale, changes in inverted sapwood electrical conductivity correspond to changes in sapwood moisture. Wavelet analyses indicated that lag times between inverted electrical conductivity and sapflow increased after storm events, suggesting that as soils wetted, reliance on internal water storage decreased, as did the time required to refill daily deficits in internal water storage. We found short time lags between sapflow and inverted electrical conductivity with dry conditions, when ponderosa pine are known to reduce stomatal conductance to avoid xylem cavitation. A decrease in diel amplitudes of inverted sapwood electrical conductivity during dry periods suggest that the ponderosa pine relied on internal water storage to supplement transpiration demands, but as drought conditions progressed, tree water storage contributions to transpiration decreased. Time-lapse ERI- and wavelet-analysis results highlight the important role internal tree water storage plays in supporting transpiration throughout a day and during periods of declining subsurface moisture.more » « less

Abstract Arctic amplification of anthropogenic climate change is widely attributed to the sea-ice albedo feedback, with its attendant increase in absorbed solar radiation, and to the effect of the vertical structure of atmospheric warming on Earth’s outgoing longwave radiation. The latter lapse rate feedback is subject, at high latitudes, to a myriad of local and remote influences whose relative contributions remain unquantified. The distinct controls on the high-latitude lapse rate feedback are here partitioned into “upper” and “lower” contributions originating above and below a characteristic climatological isentropic surface that separates the high-latitude lower troposphere from the rest of the atmosphere. This decomposition clarifies how the positive high-latitude lapse rate feedback over polar oceans arises primarily as an atmospheric response to local sea ice loss and is reduced in subpolar latitudes by an increase in poleward atmospheric energy transport. The separation of the locally driven component of the high-latitude lapse rate feedback further reveals how it and the sea-ice albedo feedback together dominate Arctic amplification as a coupled mechanism operating across the seasonal cycle.more » « less

Retelle, Michael J (Ed.)Long-term hydroclimate monitoring in Linnédalen, western Spitsbergen provides a baseline for understanding climate and environmental change in the rapidly warming 21st century climate in Svalbard. Monitoring watershed and climatological processes also provides the means for directly interpreting the annually resolved sedimentation record (varves) in proglacial Linnévatnet, which in turn, will allow for an understanding of the current hydroclimatic regime in a long-term context. Related sediment core data were submitted by our collaboration partners at the University of Massachusetts, Amherst. An automated weather station, snow depth and stream water temperature sensors, time-lapse cameras, and moorings in Linnévatnet have been deployed since 2003 in the 31 square kilometer (km2) catchment of Linnédalen. This project (2016-2023) follows hydroclimate studies initiated during the National Science Foundation - Office of Polar Programs (NSF-OPP) sponsored Svalbard Research Experience for Undergraduates (REU) which ran from 2003 to 2013 archived and research and teaching in Linnédalen while the project was affiliated with the University Centre in Svalbard 2016-2022. Data from the earlier phase of the Linnedalen monitoring project includes weather station measurements, time lapse photography, and student theses and reports was archived in the Arctic Data Center and can be found here: https://arcticdata.io/catalog/view/urn:uuid:1b96e994-20a1-4445-a327-3256c040034fmore » « less
