Abstract Day and night airborne thermal infrared image data at 5 m spatial resolution acquired with the 15-channel (0.45mum-12.2mum) Advanced Thermal Land Applications Sensor (ATLAS) over Alabama, Huntsville on 7 September, 1994 were used to study changes in signatures of urban land cover types between day night. channel number 13 (9.60 mum-10.2mum) best noise-equivalent temperature change (NEDeltaT) 0.25 C after atmospheric corrections calibration selected for use this analysis.

The Urban Climate and Resiliency-Science Working Group (i.e., WG) was convened in the summer of 2018 to explore scientific grand challenges related climate resiliency cities. WG leveraged presentations at 10th International Conference on (ICUC10) held New York City (NYC) 6–10 August as input forum. ICUC10 a collaboration between Association Climate, American Meteorological Society, World Organization. It attracted more than 600 participants from 50 countries, resulting close 700 oral poster...
Observations of planet Earth from space are a critical resource for science and society. Satellite measurements represent very large investments United States (US) agencies organize their effort to maximize the return on that investment. The US National Research Council conducts survey applications prioritize observations coming decade. most recent prioritized visible shortwave infrared imaging spectrometer multispectral thermal imager meet range needs studying Surface Biology Geology (SBG)....
Soil pH buffering capacity, since it varies spatially within crop production fields, may be used to define sampling zones assess lime requirement, or for modeling changes in soil when acid‐forming fertilizers manures are added a field. Our objective was develop procedure map this property. One‐hundred‐thirty‐six samples (0‐ 15‐cm depth) from three Georgia Coastal Plain fields were titrated with calcium hydroxide characterize differences capacity of the soils. Since relationship between and...
Abstract Land-cover and land-use (LCLU) changes have significant climate impacts in tropical coastal regions with the added complexity of occurring within context a warming climate. The individual combined effects these two factors islands are investigated by use an integrated mesoscale atmospheric modeling approach, taking northeastern region Puerto Rico as test case. To achieve this goal, ensemble simulations is performed, combining LCLU global scenarios. Reconstructed agricultural maps...
Beautiful and breezy cities on small tropical islands, it turns out, may not be exempt from the same local climate change effects urban heat island seen in large continental such as Los Angeles or Mexico City. A surprising, recent discovery indicates that this is case for San Juan, Puerto Rico, a relatively affluent coastal city of about two million inhabitants spreading rapidly into once‐rural areas around it. climatological analysis surface temperature has revealed been increasing over...
Abstract This paper focuses on the surface–atmospheric interaction in a tropical coastal city including validation of an atmospheric modeling and impact study land-cover land-use (LCLU) changes. The Regional Atmospheric Modeling System (RAMS), driven with regional reanalysis data for 10-day simulation, is used to perform San Juan metropolitan area (SJMA), one largest urban conglomerations Caribbean, which located island Puerto Rico taken as test case. model’s surface characteristics were...
Abstract The Surface Biology and Geology (SBG) concept is the first National Aeronautics Space Administration (NASA) Earth mission to develop implement systematic integration of science application needs at architecture study stage. Prior NASA planning activities presumed that measurement would encompasss so did not explicitly evaluate include applications this However, effort presented here identified, documented integrated have been included by considering research only. First, a low...
The Kent State University (KSU) spectral decomposition method provides information about the signals present in multispectral and hyperspectral images. Pre-processing steps that enhance signal to noise ratio (SNR) by 7.37–19.04 times, enables extraction of environmental captured National Aeronautics Space Administration (NASA) Glenn Research Center's, second generation, Hyperspectral imager (HSI2) into multiple, independent components. We have accomplished this pre-processing Level 1 HSI2...
Analysis of visible remote sensing data research requires removing atmospheric effects by conversion from radiance to at-surface reflectance. This can be achieved through theoretical radiative transfer models, which yield good results when well constrained field observations, although these measurements are often lacking. Additionally, models perform poorly in marine or lacustrine settings complex air masses with variable aerosols present. The empirical line method (ELM) measures reference...
Remotely sensed imagery with high spatial resolution has been used to map soil organic carbon (SOC) concentrations at a field scale greatly increased accuracy and reduced cost compared grid sampling. The procedure, however, requires each crop be sampled mapped separately. purpose of this study was determine if could further by grouping number fields based on their image similarity, then mapping them together as one group. Ten bare surface were selected from 2000 NASA ATLAS image. similarity...
A site near Tuskegee, Alabama was examined for vector-host activities of eastern equine encephalomyelitis virus (EEEV). Land cover maps the study were created in ArcInfo 9.2 from QuickBird data encompassing visible and near-infrared (NIR) band information (0.45 to 0.72 microm) acquired July 15, 2008. Georeferenced mosquito bird sampling sites, their associated land attributes site, overlaid onto satellite data. SAS 9.1.4 used explore univariate statistics generate regression models using...
