A Planetary Boundary Layer Height Climatology Derived from ECMWF Reanalysis Data (2013, methodology): “…observations from the Atmospheric Infrared Sounder (AIRS) instrument (Fetzer et al. 2004;Martins et al. 2010) or Moderate Resolution Imaging Spectroradiometer (MODIS) and Tropical Rainfall Measuring Mission (TRMM) data to derive the PBL height in selected regions (Wood and Bretherton 2004).”
Spatial variability of liquid water path in marine low cloud : The importance of mesoscale cellular convection (2006, methodology): “Estimates of the accuracy of this technique suggest that the uncertainty in each zi estimate is approximately 200–300 m (Wood and Bretherton 2004). b. Scene selection Our basic unit of analysis is a “scene,” a 256 256 km2 portion of the MODIS swath.”
On the Relationship between Stratiform Low Cloud Cover and Lower-Tropospheric Stability (2006, background): “There is evidence that the vertical gradient of liquid potential temperature (conserved for moist processes) increases as the PBL depth increases, being close to zero for shallow, well-mixed (and stratocumulus capped) marine boundary layers (MBLs) to being close to a moist adiabat for deeper PBLs do”
Moisture and dynamical interactions maintaining decoupled Arctic mixed-phase stratocumulus in the presence of a humidity inversion (2011, background): “Interestingly, mean subsidence above the upper entrainment zone is of the same order as mean subsidence in subtropical cloud-topped boundary layers (see Wood and Bretherton, 2004) and other LES simulations of AMPS (see Klein et al., 2009).”
Stratocumulus Cloud-Top Height Estimates and Their Climatic Implications (2009, background): “Cloud bases between 300 and 800 m corresponded well to the LCL, indicating well-mixed conditions that are consistent with Wood and Bretherton (2004).”
Tropical and Subtropical Cloud Transitions in Weather and Climate Prediction Models: The GCSS/WGNE Pacific Cross-Section Intercomparison (GPCI) (2011, methodology): “Some models [e.g., ECMWF, GFDL, UKMO) show a smooth and gradual evolution of the cloudy boundary layer height that, based on some previous studies, appears to be relatively realistic (e.g., Wyant et al. 1997; Wood and Bretherton 2004; von Engeln et al. 2005; Karlsson et al. 2010).”
The University of Washington Shallow Convection and Moist Turbulence Schemes and Their Impact on Climate Simulations with the Community Atmosphere Model (2009, background): “Satellite-derived cloud-top-height climatologies (e.g., Wood and Bretherton 2004) suggest that at 208S the trade inversion should remain above 1 km all the way to the coast.”
Marine boundary layer clouds at the heart of tropical cloud feedback uncertainties in climate models (2005, background): “Such a transition can occur if the SST increase is associated with a decrease of the lower tropospheric static stability and/or with an increase of the planetary boundary-layer (PBL) decoupling [Klein and Hartmann, 1993; Pincus et al., 1997; Norris, 1998a; Wood and Bretherton, 2004].”
The Epic 2001 Stratocumulus Study (2004, methodology): “The cloud-top height was similar to the satellite-derived October mean (Wood and Bretherton 2004), and the mean ship-observed liquid water path was roughly 30% larger than the October mean inferred from satellite measurements (Wood et al. 2002).”
Planetary boundary layer heights from GPS radio occultation refractivity and humidity profiles (2012, methodology): “The MODIS (Moderate Resolution Imaging Spectroradiometer) cloud-top temperature and TRMM Microwave Imager (TMI) SST are also useful to retrieve the PBL height but only in limited regions [Wood and Bretherton, 2004].”
Observational Evidence That Enhanced Subsidence Reduces Subtropical Marine Boundary Layer Cloudiness (2013, background): “1 2013 American Meteorological Society Unauthenticated | Downloaded 09/28/22 11:27 AM UTC Wood and Bretherton (2004) found that shallow, cloudyMBLs tend to be well mixed, whereas deepMBLs tend to be decoupled.”
The Distribution of Cloud Horizontal Sizes (2011, background): “As the MBL deepens, typically due to increased surface fluxes a well-mixed boundary layer that can support extensive saturated conditions near its top can no longer be maintained, and the MBL decouples (e.g., Albrecht et al. 1995; Bretherton and Wyant 1997; Wood and Bretherton 2004).”
