Abstract:
The present invention relates to a dual cap for protecting a humidity sensor of a radiosonde. The dual cap is fixed to a position where a humidity sensor of a sensing unit in a radiosonde of an aerological observation system is disposed so as to surround the humidity sensor, the dual cap including: an outer cap having a first ventilation hole formed on top thereof, a first air circulation door formed on the side periphery thereof to pass air therethrough, and a first wall formed on the side periphery thereof to close the flow of air; and an inner cap located inside the outer cap in such a manner as to be fixed to the outer cap and having a second air circulation door formed on the side periphery thereof to pass air therethrough, the second air circulation door facing the first wall of the outer cap.
Abstract:
A man packable, portable sounding kit includes, in one example, at least two balloons and at least two radiosondes each including a tether for connecting a radiosonde to a balloon. A gas container includes gas for inflating the at least two balloons. A fill hose assembly includes a balloon inflation nozzle coupled to a pressure regulator. A data transceiver unit is configured to receive and optionally to rebroadcast atmospheric weather data from the radiosonde. A case houses the balloons, radiosondes, data transceiver unit, gas container, and fill hose assembly.
Abstract:
The present invention relates to a rising-and-falling type of lower atmosphere observation and testing device, which allows precise observational result values to be determined through the use of a GPS radiosonde, since it allows accurate determination of the position of the radiosonde and the position of the ground mooring point.
Abstract:
The invention relates to a method for correcting a radiation error in atmospheric temperature measurement, particularly when using a radiosonde (1), a rocket, or a dropsonde, in which method at least one temperature measurement sensor is used in each measuring device. According to the invention, the state of motion of the sonde (1) relative to the ambient air is measured essentially simultaneously with the temperature measurement, and the result of the measurement result is used to correct the error of the temperature measurement.
Abstract:
Methods and systems for measuring atmospheric water content are provided. One method includes measuring a first air temperature and a first air pressure at a first location in a compressor, measuring a second air temperature and a second air pressure at a second location in the compressor, computing a ratio of specific heats from the first and second air temperatures and the first and second air pressures, and determining an atmospheric water content from the ratio of specific heats. Said compressor is part of an aircraft turbine engine. Said measured water content is transmitted to a weather forecast model.
Abstract:
Methods and systems for demodulation of open-loop GPS radio occultation signals are provided. An occulted GPS radio signal where the atmosphere-induced modulation on the phase is up to 180 degrees may be recorded by a radio occultation receiver. The radio signal may be concurrently received by a second receiver where the atmosphere-induced phase modulation is below 90 degrees and where the Navigation Data Message (NDM) bit sequence can be readily extracted. The extracted NDM bit sequence may be used to demodulate the occulted GPS radio signal and a 4-quadrant phase extractor may then be used to determine the phase and amplitude of the radio occultation signal. The phase and amplitude modulations after removal of NDM may be used for inversion, e.g., retrieval of the atmospheric parameters such as the bending angle, refractivity and deriving of the meteorological parameters.
Abstract:
An automated balloonsonde launcher (88) and a method for an automated balloonsonde launch are disclosed. The automated balloonsonde launcher, for example, may comprise a collapsible protective cover (60) forming an inner region for receiving a balloon, a gas inlet for receiving a gas, a gas outlet for mating with a balloon, a valve operable between the gas inlet and the gas outlet for inflating a balloon within the inner region of the protective cover. The launcher further comprises a controller that controls the valve to inflate a balloon within the protective cover, opens an opening in the protective cover and releases a balloon through the opening of the protective cover.
Abstract:
The prior art includes, for example meteorological and radiosondes, which are used to measure the prevailing atmospheric conditions. This publication discloses a sonde for sondes and a sonde. When a sonde rises to the cold layers of the atmosphere, its temperature drops to about -50 °C. The batteries used in the sonde must be able to supply the sonde's electronics with the power they require, even in such conditions. The invention exploits the fact that the soundings carried out using sondes are of a quite short duration. According to the invention, the cooling of the batteries (2) is slowed and delayed by bringing them into thermal contact with a phase-transition substance (3). The phase-transition substance is a substance in which a phase transition takes place when the temperature changes from the temperature of the storage of the arrangement or sonde to the temperature of the measuring environment. The phase-transition substance (3) can be, for example, water, which prevents the temperature of the battery (2) from dropping below 0 °C, until the water has frozen.
Abstract:
An environmental data collection system and method is provided having an internet link for providing an additional level of security for a remotely controlled data collection platform having a security alarm for protecting the platform and the environmental subject of the study. A novel lighter-than-air platform having a novel snorkel for detachably securing, mooring and providing buoyancy control is provided for the collection of data in the form of real time audio and video linked to the internet and subscribers. The novel snorkel is flexible and retractable into the novel airship to provide remote buoyancy control of the airship together with silently operating electrical motors for allowing the novel airship to be remotely controlled and moved at will to track and monitor wildlife and make environmental measurements necessary for the protection of the environment, wildlife and the operation of the novel airship. Detachable securing means provide an anti-tethering feature of the novel airship and allow the collection of data from both, an aerial perspective and a ground perspective, while providing for the collection of data from either the surface of the earth or below the surface of the water while transmitting the data to scientists, environmentalists and subscribers through the internet.
Abstract:
A system for predicting the occurrence of microburst/windshear comprising at least one sensor (520) for receiving lightning produced signals, a processor (210) for processing those received signals to produce data and generate a warning (224) when the processed data indicates that a microburst/windshear is about to occur.
