MODIS: Moderate-resolution imaging spectrometer. Earth observing system, volume 2B [PDF]

The Moderate-Resolution Imaging Spectrometer (MODIS), as presently conceived, is a system of two imaging spectroradiometer components designed for the widest possible applicability to research tasks that require long-term (5 to 10 years), low-resolution (

Mapping the density of giant trees in the Amazon

New Phytologist, EarlyView.
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...

Assessment of MISR and MODIS cloud top heights through inter-comparison with a back-scattering lidar at SIRTA [PDF]

, 2004
One year of back-scattering lidar cloud boundaries and optical depth were analysed for coincident inter-comparison with the latest processed versions of the NASA-TERRA MISR stereo and MODIS CO2-slicing operational cloud top heights. Optically thin clouds

Soil salinity characteristics using moderate resolution imaging spectroradiometer (MODIS) images and statistical analysis

Archives of Agronomy and Soil Science, 2013
Remote sensing is currently a tremendous asset in controlling and monitoring soil salinity. Moderate resolution imaging spectroradiometer (MODIS) images can be obtained daily, are free, offer more opportunities to acquire cloud-free images and may be preferred over high-resolution spatial data.

Recurrent hot droughts cause persistent legacy effects in a temperate Scots Pine forest

Plant Biology, EarlyView.
A series of hot drought events caused persistent legacy effects in a Scots Pine forest, with severe negative impacts on ecosystem carbon fluxes. Abstract Recent hot‐dry events have caused significant impacts and legacy effects in temperate ecosystems. Here, we investigate legacy effects of the 2018 hot drought on a Pinus sylvestris L.

Large Area Crops Mapping by Phenological Horizon Attention Transformer (PHAT) Method Using MODIS Time-Series Imagery

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Accurate collection of crop planting information at large area is essential for estimating agricultural productivity and ensuring food security. Different crops have varying growth cycles and phenological stages, and changes in factors such as topography,

No legacy effects of severe drought on carbon and water fluxes in a Mediterranean oak forest

Plant Biology, EarlyView.
A Mediterranean Quercus ilex forest was severely affected by a drought in 2017 but fully recovered in the following year, supported by favourable weather and growing conditions both before and after the event. Abstract Severe droughts affect vegetation through several processes, such as hydraulic failure, early leaf senescence, depletion of carbon ...

Detecting imprints of atmospheric waves in the Bering Sea with MODIS data

Oceanologia, 2016
Satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data of water leaving radiance of 859 nm with a spatial resolution of 250 m were used to investigate the impact of atmospheric gravity waves (AGWs), which manifested as stripes in clouds and
