UMBC Joint Center for Earth Systems Technology (JCET)
Browse by
The Joint Center for Earth Systems Technology (JCET) was formed under a Cooperative agreement between the Earth Science Division of NASA Goddard Space Flight Center (GSFC) and the University of Maryland, Baltimore County (UMBC) in 1995. The JCET family consists of its business staff, students, research faculty, GSFC Sponsors, appointed fellows and affiliated tenured/tenure-track faculty. JCET is an innovative center where these scientists interact in a seamless fashion with the support of an efficient business and administrative unit.

Volcanic Cloud and Aerosol Monitor (VOLCAM) for Deep Space Gateway
(2018)Frequent (~15 min) imaging of reflected solar ultra-violet (UV) and thermal ifrared (TIR) radiation of the whole Earth from cislunar vantage point offer unique possibilities to answer NASA’s Earth System Science (ESS) ... -
LIDAR PROFILING IN THE LOWER TROPOSPHERE: EXPERIENCE FROM PECAN
(EPJ, 2018)Results from the PECAN (Plains Elevated Convection at Night) campaign are discussed. In particular, the utility of simple backscatter lidars/ceilometers in quantifying atmospheric dynamics parameters and variables as well ... -
ESTIMATE OF RAIN EVAPORATION RATES FROM DUAL-WAVELENGTH LIDAR MEASUREMENTS: COMPARISON AGAINST A MODEL ANALYTICAL SOLUTION
(EPF, 2018)Rain evaporation significantly contributes to moisture and heat cloud budgets. In this paper, we illustrate an approach to estimate the median volume raindrop diameter and the rain evaporation rate profiles from dual-wavelength ... -
MIXED LAYER DEPTHS VIA DOPPLER LIDAR DURING LOW-LEVEL JET EVENTS
(EPJ, 2018)A low-level jet (LLJ) is a prominent wind speed peak in the lower troposphere. Nocturnal LLJs have been shown to transport and mix atmospheric constituents from the residual layer down to the surface, breaching quiescent ... -
Retrieval of aerosol properties and water-leaving reflectance from multi-angular polarimetric measurements over coastal waters
(The Optical Society, 2018)Ocean color remote sensing is an important tool to monitor water quality and biogeochemical conditions of ocean. Atmospheric correction, which obtains water-leaving radiance from the total radiance measured by satellite-borne ... -
An IR Sounding-Based Analysis of the Saharan Air Layer in North Africa
(2018)• Evaluated AIRS SAL detection potential given porous radiosonde network (2002–2016) • AIRS vs AIRS/AMSU WML detection rates within 5% • WML: Potent seasonal cycle, best resolved by AIRS • SAL Frequency: Well-matched ... -
Characterization of smoke and dust episode over West Africa: comparison of MERRA-2 modeling with multiwavelength Mie–Raman lidar observations
(European Geosciences Union, 2018)Observations of multiwavelength Mie–Raman lidar taken during the SHADOW field campaign are used to analyze a smoke–dust episode over West Africa on 24–27 December 2015. For the case considered, the dust layer extended from ... -
Single-footprint retrievals for AIRS using a fast TwoSlab cloud-representation model and the SARTA all-sky infrared radiative transfer algorithm
(Copernicus GmbH, 2018)One-dimensional variational retrievals of temperature and moisture fields from hyperspectral infrared (IR) satellite sounders use cloud-cleared radiances (CCRs) as their observation. These derived observations allow the ...
