20160003975 | A RADIOSONDE AND A METHOD FOR ATMOSPHERIC MEASUREMENTS PERFORMED AT AN ELEVATED TEMPERATURE - The invention relates to a method and a radiosonde. According to the method at least temperature and relative humidity of the atmosphere are measured by a radiosonde. In accordance with the invention the humidity measurement is performed continuously in an elevated temperature in order to make the measurement faster and both the elevated temperature and ambient air temperature are measured simultaneously and based on these values relative humidity is determined and the humidity sensing elements are positioned on a planar substrate. | 01-07-2016 |
20130141248 | METHOD FOR LAUNCHING AND A RADIOSONDE - A method and a radiosonde wherein the radiosonde is launched from a launching station and transmission of the radiosonde is started in order to send measurement data to a receiver. The transmission of the radiosonde is started only after a delay from the launch. | 06-06-2013 |
20130025115 | WIRELESS SENSOR UNIT AND A MAINTENANCE METHOD FOR A WIRELESS SENSOR - A wireless sensor unit and a maintenance method. The sensor unit includes a sensor capable of forming a measurement signal, electronics capable of receiving a measurement signal from the sensor and sending the signal wirelessly to a wireless network, and a power supply for providing supply voltage for the sensor and electronics. The unit is divided into two parts, a first part and a second part such that the first part includes the electronics and is may be mounted permanently to a fixed object like a wall, and second part including the power supply and the sensor. The second part is capable to be repeatedly mounted and detached to the first part. | 01-31-2013 |

20130002475 | OFF-DIAGONAL ELEMENT ECHO POWER ESTIMATOR FOR POLARIZATION WEATHER RADAR - Embodiments of the invention are directed to improving the sensitivity in polarimetric radar data. In particular, embodiments of the invention improve the sensitivity of such systems with improved post processing techniques. The sensitivity can be improved by using the co-polar elements (off diagonal elements) of the covariance matrix in power and/or reflectivity determinations. This can not only improve the sensitivity but may also enhance identification and improve quantitative estimates of precipitation. | 01-03-2013 |
