Landsat 8 Observation of the Internal Solitary Waves in the Lombok Strait

Indonesian Journal of Geography, 2019
Landsat  8,  Landsat  Data  Continuity  Mission  (LDCM)  satellite,  was  launched  on  11 February 2013 with Operation Land Imager (OLI) sensors. Tis sensor has better radiometric performance than the previous mission, which is quantized in the 12-bit ...

Landsat 8 Virtual Orange Band for Mapping Cyanobacterial Blooms

Remote Sensing, 2020
The Landsat 8 Operational Land Imager (OLI) has a panchromatic band (503−676 nm) that can be used to derive a novel virtual orange band (590−635 nm) by using the multispectral green band and red band components.

Controlling banana bunchy top disease in Benin: Crop protection strategies with socio‐economic perspectives

PLANTS, PEOPLE, PLANET, EarlyView.
Banana and plantain are vital for food security and income in West Africa, yet banana bunchy top virus (BBTV) threatens production. This study combined remote sensing, field surveys, modelling and socio‐economic analysis to assess BBTV spread and control strategies in Benin.

An Arctic sea ice concentration data record on a 6.25 km polar stereographic grid from 3 years of Landsat-8 imagery [PDF]

Earth System Science Data
The decline in Arctic sea ice in the global warming era has received much attention as a contributing factor to the changes in the weather and climate in the Arctic and beyond. The coverage of Arctic sea ice (i.e.

Evaluating anisotropy‐based Monin–Obukhov similarity theory over canopies and complex terrain

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study shows that an anisotropy‐based generalization of Monin–Obukhov surface‐layer scaling (SC23) applies readily across a wide range of atmospheric conditions with variable terrain, canopies, and land‐cover complexity. This work focuses on the scaling of velocity variances for 7 years at the 47 sites in the National Ecological Observation Network

Addressing Biases in Ice Jam Observations by Integrating Multi‐Source Data in a Forested Fluvial Landscape, Southern Quebec

River Research and Applications, EarlyView.
ABSTRACT Exhaustive long‐term and large‐scale ice jam records are scarce in most cold river environments. Many discrete events occur in small, sparsely populated river systems and are poorly represented in open‐source databases. These observation biases are transferred to predictive models of ice jams and the collective understanding of their formation

Mapping the Distribution of Total Suspended Solids (TSS) in Gondang Reservoir, Lamongan Using Multi-Temporal Landsat Imagery

Future Space
Total Suspended Solids (TSS) are defined as particles and materials suspended in water with sizes up to less than 2 µm. High TSS concentrations pose significant hazards by hindering light penetration, disrupting photosynthesis, and reducing oxygen ...

Wall‐to‐wall Amazon forest height mapping with Planet NICFI, Aerial LiDAR, and a U‐Net regression model

Remote Sensing in Ecology and Conservation, EarlyView.
Tree canopy height is a key indicator of forest biomass and structure, yet accurate mapping across the Amazon remains challenging. Here, we generated a canopy height map of the Amazon forest at ~4.8 m resolution using Planet NICFI imagery and a deep learning U‐Net model trained with airborne LiDAR data.
