ALMA Memo 326 Vertical Pro les of Soil Resistivity at Pampa La Bola and Llano de Chajnantor Locations
نویسندگان
چکیده
We report results of resistivity sounding of eight locations in the Cerro Chasc on science preserve area. The soil resistivity near the surface was found to be 1000 m at the ve locations in the Pampa La Bola area. The values at the three locations in the Llano de Chajnantor area were much higher, exceeding 3500 m. This di erence probably re ects di erences in water content in the upper soil layer due to local topography and drainage. The depths of the upper layer of broken rock found at these sites are of order a few meters, and are consistent with depths found from borehole cores obtained near each location.

ALMA Memo No. 487 Lightning Near Cerro Chascón
We present a preliminary analysis of the spatial and seasonal lightning distribution near the Cerro Chascón science preserve, probed with a space-borne imaging sensor and groundbased storm detectors. The lightning flash rate in this area is among the lowest in the world for comparable latitudes. Thunderstorms only occur around 5 days per year. Most observed lightning strikes occurred far to the...
متن کاملALMA Memo No. 448 UV intensity near AOS and OSF
UV intensity near the AOS and OSF sites in northern Chile was measured with handheld UVA and UVB radiometers and was compared with that taken at Socorro AOC, Nobeyama, and Mitaka. Typical UVA opacity was about 0.4 at Pampa La Bola near the AOS site, about 0.6 both at San Pedro de Atacama near the OSF site and at Nobeyama, and about 0.7 at Mitaka (best conditions), respectively. The UVA intensit...

Levels of radiation exposure in Chilean altiplano primarily due to cosmic rays were measured with pocket gamma ray dosimeters and a handy neutron rem counter. Comparison data were also taken at Antofagasta, Santiago, Mitaka, and on board the aircrafts to/from the site. Significant enhancement of dose rates was found at the ALMA site: Measured gamma ray dose rate (including ∼ 0.45mSv yr−1 contri...

Further analysis has been made on the millimeter and submillimeter-wave (100–1600 GHz or 3 mm – 188 μm) atmospheric opacity data taken with the Fourier Transform Spectrometer (FTS) at Pampa la Bola, 4800 m above sea level in northern Chile, which is the site of the Atacama Large Millimeter/submillimeter Array (ALMA). Time-sequence plots of millimeter and submillimeter-wave opacities show simila...

We present a baseline plan of Japanese receiver developments for the Large Millimeter Submillimeter Array (LMSA) and the Atacama Large Millimeter Array (ALMA). Two receiver cartridge layouts for ALMA band 8 (385 – 500 GHz) have been proposed based on a quasi-optical sideband separation. These cartridges will be evaluated in a secondary focal receiver system with the Atacama Submillimeter Telesc...
