Summary: Accurate estimation of canopy chlorophyll content (CCC) is crucial for agricultural production management, but current vegetation indices are affected by canopy structure. This study develops CCC-sensitive and MTA-insensitive satellite broadband vegetation indices for crop canopy chlorophyll content estimation. The identified indices show strong correlations with CCC and weak correlations with MTA, indicating their potential use for crop CCC estimation across species and seasonality.

Summary: Accurately estimating the start of season (SOS) is crucial for understanding vegetation phenology trends under climate change. However, in regions with winter snow cover, the presence of snow introduces bias into SOS detection. This study combined simulation experiments and real satellite data to investigate the effect of snow cover on vegetation index (VI) and SOS detection. The presence of snow significantly reduces VI values and increases the local gradient of the growth curve, allowing for the detection of SOS. The bias in SOS detection caused by snow cover depends on snow season end, duration, and snow-free SOS. The five VIs differed in sensitivity to snow cover in SOS detection, with NDPI/NDGI < NIRv < EVI2 < NDVI.

Summary: A partnership between Central Queensland University and the Queensland Government National Park management agency has developed a toolkit for assessing the habitat health of koalas. The toolkit includes vegetation maps derived from satellite imagery and is designed to help landholders evaluate habitat suitability and monitor conservation outcomes. Despite some limitations, the toolkit has proven to be effective in assessing habitat health at a landscape scale.

Summary: The article discusses the accuracy of yield forecasting algorithms and presents a unified methodology based on remote sensing data for crop yield prediction. The study finds that yields can be predicted using NDVI vegetation index data and meteorological data. Machine learning algorithms are used to calculate the relationship between these indicators and build a neural network for yield prediction. The research shows that multi-layer perceptron and polynomial regression have the highest prediction accuracy for all crops.

Summary: Vegetation indices (VIs) are widely used for remote sensing monitoring of vegetation vigor and growth dynamics. However, the saturation phenomenon of VIs limits their ability to characterize surface vegetation over dense canopies. In this study, two indicators were proposed to describe the saturation phenomenon, and the performance of different VIs under various conditions was evaluated using simulation and satellite data. The results showed that the simple ratio vegetation index (SR) performed best, with the highest saturation point and good characterization of surface vegetation until LAI reaches 4.

Summary: Leaf angle distribution is an important characteristic of canopy structure, but there have been few studies on direct retrieval of leaf angle distribution from remote sensing data. This study demonstrates the potential of using the red edge channels on Sentinel-2 satellite for large-scale mapping of leaf angle distribution. The results show that Sentinel-2 can accurately map the leaf angle distribution of field crops.
