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

Crop Yield Estimation Using NDVI: A Comparison of Various NDVI Metrics
The objective of this study is to examine and compare multiple Normalized Difference Vegetation Index (NDVI) metrics for estimating crop yield. There are several terms used to describe NDVI metrics including: process methods, aggregation techniques, phenological indices, and aggregation metrics.

Tule elk selection of surface water and forage is mediated by season and drought
Climate change is expected to affect arid-system ungulate populations by altering the distribution and availability of critical resources such as water and forage, particularly through more frequent and extreme droughts.

Sensitivity of GNSS-R spaceborne observations to soil moisture and vegetation [PDF]
Global navigation satellite systems-reflectometry (GNSS-R) is an emerging remote sensing technique that makes use of navigation signals as signals of opportunity in a multistatic radar configuration, with as many transmitters as navigation satellites are

Winter Conditions Influence Biological Responses of Migrating Hummingbirds
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

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

Inherent Reflectance Variability of Vegetation
With the inception of small unmanned aircraft systems (sUAS), remotely sensed images have been captured much closer to the ground, which has meant better resolution and smaller ground sample distances (GSDs).
