A defined hook echo is visible in the radar photographs taken by the WBO; the tornado passed less than 1 mile (1.6 kilometres) to the south of the radar site, cutting off power to the site and preventing further radar observations as it moved to the southeast. [23]
The state of Texas supported the implementation of 20 radar facilities, each with a 200-mile-wide (320 km) radius, that proved successful in reducing death tolls in later tornadoes. [13] The system was known as the Texas Radar Tornado Warning Network and also included communications between weather officials, storm spotters, and local officials ...
In addition to monitoring city lights, these photos are a life saving asset in the detection and monitoring of fires. Not only do the satellites see the fires visually day and night, but the thermal and infrared scanners on board these weather satellites detect potential fire sources below the surface of the Earth where smoldering occurs.
The company is based in San Francisco, California and was founded in 1995 as an offshoot of the University of Michigan internet weather database. The name is a reference to the 1960s radical left-wing militant organization the Weather Underground, which also originated at the University of Michigan.
A tornado warning was issued for the area roughly 30 minutes prior to the tornado's arrival, and the relatively low loss of life was attributed to this lead time. [80] A tornado emergency was declared at 7:24 p.m. CDT (00:24 UTC) for the city shortly before the tornado struck. [81] Four people were killed in the town and many more were injured.
Its major payload is an X-band (3.1 cm) radar sensor, with different modes of operation, which allows it to provide multiple imaging modes for recording images with different swath width, resolution and polarizations, see the figure for more details. In stripmap mode (spatial resolution of 3m), it needs 10 weeks to map global Earth's landmass.
Pattern-of-life analysis is a method of surveillance that documents or understands the habits of a person or population. Motives may include security, profit, scientific research, regular censuses, and traffic analysis. The data of interest may reflect anything in a person or persons' life: their travels, purchases, internet browsing habits ...
The goal of this project was to produce a satellite for earth observation by way of a Synthetic Aperture Radar, which is an advanced radar sensor and powerful microwave instrument capable of producing high quality images of the Earth during day or night and across a wide range of weather conditions including cloud cover, smoke, and haze.
