POLDER (POLarization and Directionality of the Earth's Reflectances) is a passive optical imaging radiometer and polarimeter developed by the French space agency CNES.
The device was designed to observe solar radiation reflected by Earth's atmosphere, including studies of tropospheric aerosols, sea surface reflectance, bidirectional reflectance distribution function of land surfaces, and the Earth Radiation Budget.
POLDER has a mass of approximately 30 kilograms (66 lb), and has a power consumption of 77 W in imaging mode (with a mean consumption of 29 W).
POLDER utilizes a push broom scanner. The device's optical system uses a telecentric lens and a charged coupled device matrix with a resolution of 242x548 pixels. The focal length is 3.57 millimetres (0.141 in) with a focal ratio of 4.6. The field of view ranges from ±43° to ±57°, depending on the tracking method.
The device scans between 443 and 910 nm FWHM, depending on the objective of the measurement. The shorter wavelengths (443–565 nm) typically measure ocean color, whereas the longer wavelengths (670–910 nm) are used to study vegetation and water vapor content.
Blake is a surname or a given name which originated from Old English. Its derivation is uncertain; it could come from "blac", a nickname for someone who had dark hair or skin, or from "blaac", a nickname for someone with pale hair or skin. Another theory is that it is a corruption of "Ap Lake", meaning "Son of Lake".
Blake was the name of one of the 14 Tribes of Galway in Ireland. These Blakes were descendants of Richard Caddell, alias Blake, who was involved in the Norman invasion of Ireland in 1169. As such a long present foreign name it became known as de Bláca in Irish.
The origins of the name Blake are also considered to be Old Norse, first appearing in Yorkshire, England, possibly derived from the word Blaker, referring to a village and a former municipality of Akershus county, Norway (east of Oslo).
Blake often refers to the British poet, painter and printmaker William Blake (1757–1827) or to the contemporary figurative artist Blake.
In chess, the player who moves first is referred to as "White" and the player who moves second is referred to as "Black". Similarly, the pieces that each conducts are called, respectively, "the white pieces" and "the black pieces". The pieces are often not literally white and black, but some other colors (usually a light color and a dark color, respectively). The 64 squares of the chessboard, which is colored in a checkered pattern, are likewise referred to as "white squares" or "light squares" on the one hand, and "black squares" or "dark squares" on the other. In most cases, the squares are not actually white and black, but a light color and a contrasting dark color. For example, the squares on plastic boards are often off-white ("buff") and green, while those on wood boards are often light brown and dark brown.
In old chess writings, the sides are often called Red and Black, because those were the two colors of ink then commonly available when hand-drawing or printing chess position diagrams.
Black: The Man From Darkness is a 2004 Indian Malayalam crime thriller film written and directed by Ranjith, and produced by Lal. It deals with the underworld operations in Kochi.
