Three-dimensional fields (latitude — altitude — local time) of temperature and aerosol in the upper clouds, obtained from the Venera-15 IR spectrometry data, were studied to search for the solar-related structures.
The Observer is offering five lucky readers the chance to win a pair of tickets to one of five 2016 UK music festivals: Field Day, Latitude, Green Man, V or Bestival.
Field Day, Latitude, Secret Garden Party, Visions, Green Man, Reading & Leeds Old-school and righteous 90s-style punk from the young and fiery Radke brothers from Missouri, headbanging with abandon and yet socially conscious.
On the field, the latitude and longitude of each sampling point were taken with a GPS.
This regional factor accounts for the increase of the Earth's main magnetic field with latitude and is given by (see for example Love and Constable 2003, their Equation 48): F_{latitude}=1+3sin(lat)^{2}, (18).
173 days of good backscatter from all four radars have been analysed during the period 1982 to 1986, from which the average ionospheric divergence electric field versus latitude and time is calculated.
The geographical position of each field (as latitude, longitude and altitude) was determined using the Global Positioning System (GPS).
(The geopotential, Φ z), is the work needed to raise a unit mass a vertical distance z from mean sea level and accounts for the variation of the earth's gravitational field with latitude and elevation.
These dynamos are the primary sources of the low-latitude electric field, but high-latitude processes also contribute and are discussed as well.
It's pouring with rain, I'm standing in a field at the Latitude festival that can probably take 6,000 people, but there are only about 1,000 of us.
