A Case Study of Nitrogen Saturation in Western U.S. Forests

The Scientific World Journal, 2001
Virtually complete nitrification of the available ammonium in soil and nitrification activity in the forest floor are important factors predisposing forests in the San Bernardino Mountains of southern California to nitrogen (N) saturation.

Eruptive Behaviour of Forest Fires [PDF]

, 2010
A critical review of the mechanisms that are described in the literature to explain the onset and development of eruption or blow up in forest fires is presented, given their great relevance for fire safety, particularly in canyons. The various processes

A framework for use of wireless sensor networks in forest fire detection and monitoring [PDF]

, 2012
Forest fires are one of the main causes of environmental degradation nowadays. Current surveillance systems for forest fires lack in supporting real-time monitoring of every point of a region at all times and early detection of fire threats.

Incorporating Short-Term Forecast Mean Winds and NWP Maximum Gusts into Effective Wind Speed for Extreme Weather-Aware Wildfire Spread Prediction

Fire
Because wildfire spread is strongly influenced by instantaneous gusts, models that use only mean wind speed typically underestimate spread. In contrast, incorporating suppression effects often leads to overestimation.
