Satellite‐Observed Vegetation Responses to Intraseasonal Precipitation Variability

Geophysical Research Letters, 2022
There is limited understanding of how vegetation responds to intraseasonal modes of rainfall variability despite their importance in many tropical regions.

Using SMAP and SMOS vegetation optical depth to measure crop water in vegetation

, 2020
NASA's Soil Moisture Active Passive (SMAP) and European Space Agency's (ESA) Soil Moisture Ocean Salinity (SMOS) are two microwave remote sensing satellites. They were originally designed to measure soil moisture, but with an algorithm that already retrieves vegetation optical depth (VOD), they could also be used for vegetation measurements. VOD is the

Mapping Carbon Stocks In Central And South America With Smap Vegetation Optical Depth

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
Mapping carbon stocks in the tropics is essential for climate change mitigation. Passive microwave remote sensing allows estimating carbon from deep canopy layers through the Vegetation Optical Depth (VOD) parameter. Although their spatial resolution is coarser than that of optical vegetation indices or airborne Lidar data, microwaves present a higher ...

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

The Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

L-Band Vegetation Optical Depth for Crop Phenology Monitoring and Crop Yield Assessment

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
Vegetation Optical Depth (VOD) at L-band is highly sensitive to the water content and above-ground biomass of vegetation. Hence, it has great potential for monitoring crop phenology and for providing crop yield forecasts. Recently, the Multi-Temporal Dual Channel Algorithm (MT -DCA) has been proposed to retrieve L-band VOD from Soil Moisture Active ...

Under the Shade of a Coolabah Tree: A Second Cache of Tulas From the Boulia District, Western Queensland

Archaeology in Oceania, EarlyView.
ABSTRACT This paper reports on the excavation of a cache of stone artefacts, buried on the bank of a waterhole or ‘billabong’ in central western Queensland. This is an extremely rare find, and yet it is the second such site to be reported within less than a 10 km radius.

Gleaning the Rocky Shore? 2500 Years of Coastal Resource Use at Red Bluff 1, GunaiKurnai Country, SE Australia

Archaeology in Oceania, EarlyView.
ABSTRACT Shell middens in Gippsland along the eastern half of Victoria's coastline have usually been characterised as small, short‐duration camp sites with relatively low shell densities and low taxonomic diversity. Here we present new excavation results from a dense, high‐diversity site at Red Bluff near the eastern end of GunaiKurnai Country, a ...

Sentinel-1 vegetation optical depth retrievals over the international soil moisture network

International Journal of Digital Earth
Vegetation optical depth (VOD), a microwave-based vegetation index for vegetation water content and biomass, is primarily retrieved from low spatial resolution passive microwave data, and few studies have focused on VOD retrievals from active microwave ...

Graman Revisited Once Again: A Reanalysis of the Late Holocene Legacy Faunal Assemblage From GB4 Rockshelter, New South Wales

Archaeology in Oceania, EarlyView.
ABSTRACT The archaeological site Graman B4 provided one of the first records of substantial dietary change in ancient Australian Aboriginal society. Initial examination of the faunal remains from this site suggested that Late Holocene hunters reduced their focus on high‐ranked kangaroos to increasingly rely on arboreal possums; and that these ...

Research Note:The comparison of two models that determine the effects of a vegetation canopy on passive microwave emission [PDF]

Hydrology and Earth System Sciences, 1999
Two contrasting models are used to account for the effects of vegetation on microwave emission from the soil. These are: a simple model which requires two empirically derived parameters as input data (optical depth and single scattering albedo); and a ...
