Biases in droplet radii and optical depths of marine stratocumulus retrieved from MODIS imagery

Creator:: Boeke, Robyn C.
Abstract:: The 2007 Intergovernmental Panel on Climate Change assessment established that the effect of clouds on climate contributes the largest uncertainty in predicting the future climate. Satellite observations provide an opportunity for learning about the behavior of clouds. This thesis seeks to assess the accuracy of cloud properties retrieved from multispectral...

Properties of marine stratus and stratocumulus derived using collocated MODIS and CALIPSO observations

Creator:: Hayes, Christopher R.
Abstract:: Adiabatic parcel models suggest specific relationships between cloud thickness and cloud properties. Such relationships govern cloud radiative forcing and thus cloud feedbacks in the climate system. Current remote sensing techniques work well at measuring these properties in low-level cloud systems that are overcast. Significant biases exist, however, when measuring cloud...

Identification of layered cloud occurrences from the Lidar In-Space Technology Experiment and advanced very high resolution radiometer imagery

Creator:: Stevermer, Amy J.
Abstract:: Realistic assessment of the vertical distribution of clouds, particularly the occurrence of multi-layered systems, is critical for accurate calculations of radiative transfer in general circulation models. Such information is also useful in the design and improvement of satellite retrieval techniques. Current methods for retrieving cloud properties from satellite data assume...

Improved determination of cloud-free radiances for oceans

Creator:: Burden, Arthur R.
Abstract:: Improvements have been made to the spatial coherence method for automatically determining cloud-free ocean radiances in satellite imagery by incorporating the spectral signatures of reflecting surfaces. The spatial coherence method relies on the fact that small-scale cloud-free regions typically exhibit uniform emission and uniform reflection. While small-scale overcast regions typically...

Toward the estimation of errors in cloud cover derived by threshold methods

Creator:: Chang, Fu-Lung
Abstract:: The accurate determination of cloud cover amount is important for characterizing the role of cloud feedbacks in the climate system. Clouds have a large influence on the climate system through their effect on the earth's radiation budget. As indicated by the NASA Earth Radiation Budget Experiment (ERBE), the change in...

Estimating ground cover via spectral data

Creator:: Axness, Daniel S.
Abstract:: Potato ground cover and spectral data were measured in the Columbia Basin during the 1990 growing season. Three spectral were correlated with ground cover; normalized difference, near infrared-red ratio, and the first derivative of the spectral curve at 750 nm. All models were statistically significant at the 99% level. Normalized...

Satellite infrared measurement of sea surface temperature : empirically evaluating the thin approximation

Creator:: Kowalski, Andrew S.
Abstract:: Satellite technology represents the only technique for measuring sea surface temperatures (SSTs) on a global scale. SSTs are important as boundary conditions for climate and atmospheric boundary layer models which attempt to describe phenomena of all scales, ranging from local forecasts to predictions of global warming. Historical use of infrared...

Estimating volume and value on standing timber in hybrid poplar plantations using terrestrial laser scanning : a case study

Creator:: Barnett, Jennifer S.
Abstract:: Terrestrial laser scanning (TLS) may provide a way to increase timber value recovery by replacing manual timber cruising with a simple-to-use, cost-effective alternative. TLS has been studied in several trials worldwide. Past studies have not compared TLS based estimates with mill estimates of stem value and volume. Three differently stocked...

Bright air : geoprocessing thermal imagery to map the nocturnal dynamics of the boundary layer in a mountain valley

Creator:: Johnson, Christopher
Abstract:: A thermal infrared (TIR) camera is used to remotely sense the foliage temperature in a mountain valley. The foliage temperature is used as a proxy for air temperature and can be used to study and map the dynamics of the nocturnal, weak-wind boundary layer in this valley. All radiative flux...

Lasers in the Sky : Distributed Temperature Sensing and a Micro-Meteorological Approach to Quantifying Evapotranspiration

Creator:: Predosa, Robert
Abstract:: Lower atmospheric flux measurements are a difficult subset of atmospheric data to accurately collect. The interplay of cost, precision, specialty, resolution and repeatability compound an already difficult experimental problem. In response to this, a new, novel instrumentation approach to measuring within the atmospheric boundary layer (ABL) is introduced. The combination...
