Effects of Planetary Boundary Layer Parameterizations on CWRF Regional Climate Simulation

January 8, 2012

Researchers: Shuyan Liu and Xin-Zhong Liang

Planetary Boundary Layer (PBL) parameterizations incorporated in CWRF (Climate extension of the Weather Research and Forecasting model) were first evaluated by comparing simulated PBL height diurnal cycles with observation at ARM Atmospheric Radiation Measurement) SGP (Southern Great Plains) site. Among the seven evaluated PBL schemes, two (CAM, UW) are new in CWRF while the other 5 are original WRF schemes. MYJ, QNSE and UW determine the PBL heights based on turbulent kinetic energy (TKE)

Satellite Sea Surface Salinity Error in the Tropics

January 8, 2012

Researchers: Busalacchi, G. Alory2, P. Arkin1, J. Ballabrera-Poy3, T. Delcroix4, E. Hackert1, J. Janowiak1, R. Mu

A key component of the effort to fully utilize Aquarius and SMOS data will be to determine SSS error fields over tropical oceans. Estimating the spatial distribution of SSS Signal to Noise Ratio (SNR) will help answer where exploitable information can be extracted from Aquarius/SMOS since high SNR corresponds to low observational error and increased impact of SSS data assimilation for ocean/coupled models.

Using Ecosystem Functional Types as Lower Boundary Conditions in Simulations of Droughts in Southern South America

January 8, 2012

Researchers: Omar V. Muller, Ernesto H. Berbery, Domingo Alcaraz-Segura

In this work we examine the advantages of using Ecosystem Functional Types as a replacement of conventional land cover types in WRF/Noah. EFTs are de ned on a yearly basis, therefore, they can reproduce vegetation changes resulting from either land use or natural changes.

Presented: WCRP Open Science Conference: Climate Research in Service to Society, 24-28 October 2011, Denver, CO, USA

*Note: Hugo Berbery student Omar Muller, received an award for “Best Scientific

Modulation of Cold Season US Daily Precipitation by the MJO

January 8, 2012

Researchers: Emily J. Becker, Ernesto Hugo Berbery, and R. Wayne Higgins

This study examines the characteristics of cold season (November – March) daily precipitation over the contiguous United States during active periods of the Madden-Julian Oscillation (MJO).

Presented: WCRP Open Science Conference, Denver, CO, USA, October 24-28, 2011.

Geolocation Error for NOAA POES Microwave Satellite Data

January 8, 2012

Researchers: Isaac Moradi, Huan Meng, Ralph Ferraro

In this study, we investigated and corrected the geolocation errors of the observations from AMSU-A, -B and Microwave Humidity Sounder (MHS) onboard NOAA-15 to 19.

Presented: AGU Fall Meeting, San Francisco, CA, USA, December 2011.

Marine Phytoplankton Phenology from Satellite Ocean Color Measurements

January 8, 2012

Researchers: Christopher W. Brown, Mathew R. P. Sapiano, Stephanie Schollaert Uz2 and Marco Vargas

This work builds on our recent article which presented a statistical technique for modeling phytoplankton blooms in the North Atlantic. Here, we extend this technique to the global domain and higher temporal and spatial resolution.

Presented: NASA Carbon Cycle & Ecosystems Joint Science Workshop,
3-6 october 2011, Alexandria, VA, USA.

Post-Publication: The Future of Z. Li’s Ten-Year Aerosol Study

January 5, 2012

It’s been three months since Zhanqing Li and his team released their groundbreaking study on air pollution, and they’re still feeling the effects. Sitting in his corner office at ESSIC, Li excitedly Googles the terms “Li,” “pollution,” and “precipitation,” and sits back as the screen regurgitates millions of related links. Almost all of them are tied to his study, and as he scrolls down the page his own name flashes in front of him over and over again. The same search in …
