Modelling fire occurrence at regional scale. Does vegetation phenology matter? [PDF]

open access: yes, 2015
Through its influence on biomass production, climate controls fuel availability affecting at the same time fuel moisture and flammability, which are the main determinants for fire ignition and propagation.

Local forest structure variability increases resilience to wildfire in dry western U.S. coniferous forests. [PDF]

open access: yes, 2020
A 'resilient' forest endures disturbance and is likely to persist. Resilience to wildfire may arise from feedback between fire behaviour and forest structure in dry forest systems.

Relationship between densification and NDVI loss. A study using the Google Earth Engine at local scale

open access: yesEnvironmental & Socio-economic Studies, 2022
Latin American cities are amongst those with the highest rates of urbanization in the world. This process has involved their territorial expansion as well as the densification of some of its neighborhoods, in mainly central areas. This is the case of the

Assessing water availability in Mediterranean regions affected by water conflicts through MODIS data time series analysis [PDF]

open access: yes, 2019
Water scarcity is a widespread problem in arid and semi-arid regions such as the western Mediterranean coastal areas. The irregularity of the precipitation generates frequent droughts that exacerbate the conflicts among agriculture, water supply and ...

Winter Conditions Influence Biological Responses of Migrating Hummingbirds

open access: yes, 2016
Conserving biological diversity given ongoing environmental changes requires the knowledge of how organisms respond biologically to these changes; however, we rarely have this information. This data deficiency can be addressed with coordinated monitoring

Bayesian Method for Building Frequent Landsat-Like NDVI Datasets by Integrating MODIS and Landsat NDVI [PDF]

open access: yesRemote Sensing, 2016
Studies related to vegetation dynamics in heterogeneous landscapes often require Normalized Difference Vegetation Index (NDVI) datasets with both high spatial resolution and frequent coverage, which cannot be satisfied by a single sensor due to technical limitations.

Cutting Through the Green: A Case for Grassland Archaeology Using UAV Multispectral Data

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Advances in low‐altitude remote sensing are needed to improve the effectiveness of archaeological prospection in the Netherlands. The geomorphological situation and land use history make applying various remote sensing and geophysical technologies particularly challenging.
