Tracking vegetation phenology across diverse North American biomes using PhenoCam imagery: A new, publicly-available dataset
TL;DR: In this article, the authors presented a series of datasets, together consisting of almost 750 years of observations, characterizing vegetation phenology in diverse ecosystems across North America, derived from conventional, visible-wavelength, automated digital camera imagery collected through the PhenoCam network, with RGB (red, green, blue) colour channel information, with means and other statistics calculated across a region-of-interest (ROI) delineating a specific vegetation type.

TL;DR: In this article, the authors quantify the strength of the interactions between gappy eddy covariance flux and micrometeorological measurements at multiple frequencies while expressing time series variance in few energetic wavelet coefficients, offering a low-dimensional view of the response of terrestrial carbon flux to climate variability.

TL;DR: The FLUXNET-CH4 dataset as mentioned in this paper is the first open-source global dataset of CH4 EC measurements and includes half-hourly and daily gap-filled and non-gap-filled aggregated CH4 fluxes and meteorological data from 79 sites globally: 42 freshwater wetlands, 6 brackish and saline wetlands, 7 formerly drained ecosystems, 7 rice paddy sites, 2 lakes and 15 uplands.

TL;DR: In this article, the authors introduce an ecosystem-scale analog of the pressure volume curve, the non-linear relationship between average leaf or branch water potential and water content commonly used in plant hydraulics.
A Simple Two-dimensional Parameterisation for Flux Footprint Predictions
TL;DR: In this paper, a two-dimensional footprint model for flux footprint prediction is proposed, based on a novel scaling approach for the crosswind distribution of the footprint and on an improved version of footprint parameterisation of Kljun et al.

Criteria for the selection of stochastic models of particle trajectories in turbulent flows
TL;DR: In this paper, the relationships between the various criteria are examined for a very general class of models and it is shown that most of the criteria are equivalent and also how a model can be designed to satisfy these criteria exactly and to be consistent with inertial-subrange theory.
