Characteristics of Aerosol Spectral Optical Depths over Manora Peak − A High Altitude Station in the Central Himalayas

We present, for the first time, spectral behaviour of aerosol optical depths (AODs) over Manora Peak, Nainital located at an altitude of ∼ 2 km in the Shivalik ranges of central Himalayas. The observations were carried out using a Multi-Wavelength solar Radiometer during January to December 2002. The main results of the study are extremely low AODs during winter, a remarkable increase to high v...

Rayleigh Lidar Measurements of the Temporal Frequency and Vertical Wavenumber Spectra in the Mesosphere over the Rocky Mountain Region

Temporal and spatial spectral analysis techniques were applied to lidar data collected over a period of 18 months above the Rocky Mountain region at an altitude range from 45 to 70 km by a Rayleigh lidar system located in Logan, Utah (41.7øN, 111.8øW). Examination of the averaged temporal frequency F(co) and vertical wavenumber F(m) spectra showed spectral slope values of1.49 + 0.03 and -2.3 + ...

Lidar systems for precision navigation and safe landing on planetary bodies

The ability of lidar technology to provide three-dimensional elevation maps of the terrain, high precision distance to the ground, and approach velocity can enable safe landing of robotic and manned vehicles with a high degree of precision. Currently, NASA is developing novel lidar sensors aimed at needs of future planetary landing missions. These lidar sensors are a 3-Dimensional Imaging Flash...

On the altitude dependence of the spectral characteristics of decametre-wavelength E region backscatter and the relationship with optical auroral forms

Observations of E region backscatter by the Iceland East SuperDARN HF radar from the 30 minute period 2330 to 2400 UT on 13 September 1999 are presented, along with simultaneous observations of auroral luminosity from two all-sky cameras. Interferometric techniques are employed to estimate the altitude of origin of each echo observed by the radar. Under investigation is a region of backscatter ...

Aerosol Characterization over a High Altitude Location in Central Himalayas

Our climate is strongly influenced by the manner in which solar radiation is absorbed and scattered in the Earth’s atmosphere. Atmospheric aerosols play an important role in modifying the radiation budget of the earth-atmosphere system. Aerosols have a direct impact on the atmosphere as they scatter and absorb solar and infrared radiations and indirectly affect the size distribution of cloud dr...
