Chemistry & Biochemistry Faculty Publications
The impact of volcanic eruptions on water vapour in the high-latitude upper troposphere is studied using deseasonalized time series based on observations by the Atmospheric Chemistry Experiment (ACE) water vapour sensors, namely MAESTRO (Measurements of Aerosol Extinction in the Stratosphere and Troposphere Retrieved by Occultation) and the Fourier Transform Spectrometer (ACE-FTS). The two eruptions with the greatest impact on the high-latitude upper troposphere during the time frame of this satellitebased remote sensing mission are chosen. The Puyehue-Cordón Caulle volcanic eruption in June 2011 was the most explosive in the past 24 years and is shown to be able to account …

CCPO Publications
We present simulation results from a version of the Regional Ocean Modeling System modified for ice shelf/ocean interaction, including the parameterisation of basal melting by molecular diffusion alone. Simulations investigate the differences in melting for an idealised ice shelf experiencing a range of cold to hot ocean cavity conditions. Both the pattern of melt and the location of maximum melt shift due to changes in the buoyancy-driven circulation, in a different way to previous studies. Tidal forcing increases both the circulation strength and melting, with the strongest impact on the cold cavity case. Our results highlight the importance of including …

Modeling Moisture Content Of Fine Dead Wildland Fuels: Input To The Behave Fire Prediction System, United States Department Of Agriculture, Forest Service
Wildfires
A method for predicting the time-dependent nature of fine fuel moisture is badly needed to support fire behavior prediction systems used in fire management. Of the models available, none met all the requirements of the BEHAVE fire behavior prediction system. The Canadian Fire Fuel Moisture Code (FFMC) came closest to meeting our needs and was selected as a base model. Improvements to the FFMC were concentrated on providing a means of accounting for annual and diurnal variation due to solar heating of woody fuels. This was necessary because the FFMC was developed for fuels located within forest stands, a generally …

Llaffs - A Lightning-Locating And Fire-Forecasting System, United States Department Of Agriculture, Forest Service
Forestry
This publication contains programs and documentation to implement an algorithm for calculating lightning fire probability. This calculation is based on a model originally developed for the National Fire-Danger Rating System. The model algorithm estimates the probability that a lightning discharge from cloud to ground will ignite a fire in fuels at the ground terminus of the lightning. Probability is estimated using variables that are measures of the fuel state and type, rain, and lightning. Details of the model can be found in Fuquay and others (1979), Latham (1979), and Fuquay (1980).
Grazing On National Forest System Lands: Cost Of Increasing Capacity In The Northern Region, United States Department Of Agriculture, Forest Service
Grazing On National Forest System Lands: Cost Of Increasing Capacity In The Northern Region, United States Department Of Agriculture, Forest Service
Forestry
Sample grazing allotments on Ranger Districts in the Northern Region (USDA Forest Service) were surveyed by questionaire to determine the feasibility of increasing grazing capacity through additional range improvements. The survey included an inventory of existing grazing capacity and the specific kind and cost of proposed improvements. Costs of improvements were amortized and aggregated for each Forest Service Planning Area. The resulting costs were compared with the increased grazing capacity measured in animal unit months (AUM) to determine the cost per additional unit of capacity.
