The role of remote sensing in monitoring global bulk tropospheric temperatures
Autor: Roy W. Spencer, John R. Christy, William B. Norris
Publikováno v: International Journal of Remote Sensing. 32:671-685
The IPCC AR4 (2007) discussed bulk tropospheric temperatures as an indicator of atmospheric energy content. Here, we examine the latest publications about, and versions of, the AR4 data sets. The metric studied is the trend that represents the averag

Surface Temperature Variations in East Africa and Possible Causes
Autor: John R. Christy, Richard T. McNider, William B. Norris
Publikováno v: Journal of Climate. 22:3342-3356
Surface temperatures have been observed in East Africa for more than 100 yr, but heretofore have not been subject to a rigorous climate analysis. To pursue this goal monthly averages of maximum (TMax), minimum (TMin), and mean (TMean) temperatures we

Discontinuity Issues with Radiosonde and Satellite Temperatures in the Australian Region 1979–2006
Autor: John R. Christy, William B. Norris
Publikováno v: Journal of Atmospheric and Oceanic Technology. 26:508-522
The temperature records of 28 Australian radiosonde stations were compared with the bulk-layer temperatures of three satellite products of The University of Alabama in Huntsville (UAH) and Remote Sensing Systems (RSS) for the period 1979–2006. The

Satellite and VIZ–Radiosonde Intercomparisons for Diagnosis of Nonclimatic Influences
Autor: William B. Norris, John R. Christy
Publikováno v: Journal of Atmospheric and Oceanic Technology. 23:1181-1194
Radiosonde datasets of temperature often suffer from discontinuities due to changes in instrumentation, location, observing practices, and algorithms. To identify temporal discontinuities that affect the VIZ/Sippican family of radiosondes, the 1979

Estimation of Tropospheric Temperature Trends from MSU Channels 2 and 4
Autor: William D. Braswell, John R. Christy, Roy W. Spencer, William B. Norris
Publikováno v: Journal of Atmospheric and Oceanic Technology. 23:417-423
The problems inherent in the estimation of global tropospheric temperature trends from a combination of near-nadir Microwave Sounding Unit (MSU) channel-2 and -4 data are described. The authors show that insufficient overlap between those two channel

Methodology and Results of Calculating Central California Surface Temperature Trends: Evidence of Human-Induced Climate Change?
Autor: Kelly T. Redmond, John R. Christy, William B. Norris, Kevin P. Gallo
Publikováno v: Journal of Climate. 19:548-563
A procedure is described to construct time series of regional surface temperatures and is then applied to interior central California stations to test the hypothesis that century-scale trend differences between irrigated and nonirrigated regions may

On the Behavior of the Stable Boundary Layer and the Role of Initial Conditions
Autor: David E. England, William B. Norris, Mark J. Friedman, William M. Lapenta, Xingzhong Shi, M. P. Singh, Richard T. McNider
Publikováno v: Pure and Applied Geophysics. 162:1811-1829
Previous studies of the stable atmospheric boundary layer using techniques of nonlinear dynamical systems (MCNIDER et al., 1995) have shown that the equations support multiple solutions in certain parameter spaces. When geostrophic speed is used as a

Error Estimates of Version 5.0 of MSU–AMSU Bulk Atmospheric Temperatures
Autor: David E. Parker, William D. Braswell, Roy W. Spencer, John R. Christy, William B. Norris
Publikováno v: Journal of Atmospheric and Oceanic Technology. 20:613-629
Deep-layer temperatures derived from satellite-borne microwave sensors since 1979 are revised (version 5.0) to account for 1) a change from microwave sounding units (MSUs) to the advanced MSUs (AMSUs) and 2) an improved diurnal drift adjustment for t
