Optimizing Ball‐Milled Composites for Fast Energy Release Under Shock Compression

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Microparticle additives containing both Al fuel and oxidizer, fabricated by arrested reactive milling (ARM), could potentially increase the power of energetic materials such as HMX because they contain premixed fuel and oxidizer. Optimizing shock reactivity requires exploring a vast parametric space encompassing composition, milling parameters

Sources of uncertainties in modelling black carbon at the global scale [PDF]

, 2010
Our understanding of the global black carbon (BC) cycle is essentially qualitative due to uncertainties in our knowledge of its properties. This work investigates two source of uncertainties in modelling black carbon: those due to the use of different ...

Laboratory, simulated‐use, and field evaluation of non‐insecticidal consumer products for indoor pest management: a freeze‐spray aerosol, light traps, and an ‘insect repellent’ lamp

Pest Management Science, EarlyView.
Control efficacy of three types of non‐insecticidal consumer products were examined in laboratory, simulated‐use, and field conditions. Freeze spray and ‘repellent lamp’ showed limited efficacy, whereas various results in attraction in light trap were reported.

Relative humidity and its effect on aerosol optical depth in the vicinity of convective clouds

Environmental Research Letters, 2013
The hygroscopic growth of aerosols is controlled by the relative humidity (RH) and changes the aerosols’ physical and hence optical properties. Observational studies of aerosol–cloud interactions evaluate the aerosol concentration using optical ...

Analysis of the fractional scattering contribution in the forward peak for multicomponent systems

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Derivation and justification of mixing rules for multicomponent systems. A novel formulation of the delta‐Eddington scaling rule. Analytical guidance for comparing radiative transfer results. Abstract The widely used δ‐Eddington approximation improves the accuracy of radiative transfer calculations by representing the fraction of scattering into the ...

Site Specific Aerosol Optical Thickness Characteristics over Mysore

Aerosol and Air Quality Research, 2008
As a part of Indian Space Research Organization’s RESPOND programme, a study has been carried out on clear sky days of the winter months December 2005 and January 2006. Spectral Aerosol Optical Thicknesses (AOT) were measured with a MICROTOPS II sun photometer at four sites of specific topography: a hill top, busy downtown, a calm water bed, and ...

Combining visible and infrared radiometry and lidar data to test simulations in clear and ice cloud conditions [PDF]

, 2010
Measurements taken during the 2003 Pacific THORPEX Observing System Test (P-TOST) by the MODIS Airborne Simulator (MAS), the Scanning High-resolution Interferometer Sounder (S-HIS) and the Cloud Physics Lidar (CPL) are compared to simulations performed ...

Characteristics of upper‐level updrafts and downdrafts in the anvils of tropical deep convective clouds

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study investigates the thermodynamic and microphysical characteristics of updrafts and downdrafts of tropical deep convective anvil clouds using in situ measurements. We found that parts of the downdrafts are in ice supersaturation in these clouds.

Further development of adaptive parameter tuning in the numerical weather prediction models of Deutscher Wetterdienst

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The introduction of adaptive parameter tuning in the numerical weather prediction models of DWD in 2022 substantially improved the forecast quality of near‐surface variables like 2‐m temperature and 2‐m humidity. Since 2023, refinements and extensions, primarily affecting the surface evaporation and its diurnal cycle, have led to further advances ...

Enhancing severe convection forecasts with microwave radiance assimilation in limited‐area models

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Microwave satellite radiances remain largely underexploited in convection‐permitting limited‐area models. We assess the assimilation of humidity‐sensitive radiances from the MHS instrument in the operational ICON‐2I model, improving the precipitation forecast of a severe convective event over the Marche region, Italy, substantially by correcting ...
