When compared with co-located data from the geosynchronous Earth orbit (GEO) and the low Earth orbit (LEO) observations, the consistency of the new ocean cloud mask algorithm has increased by 4∼10% and 4∼6% in the glint center and granule edges respectively. The thresholds are derived as a function of glint angle. Outside the sunglint regions, a dynamic reflectance threshold for the Rayleigh corrected 780 nm reflectance is applied. Over sunglint regions (glint angle ≤25°), the algorithm utilizes EPIC’s oxygen (O 2) A-band ratio (764/780 nm) in addition to the 780 nm reflectance observations in masking tests. This paper presents an improved EPIC ocean cloud masking algorithm (Version 3). Clear sky ocean surface reflectance from visible channels over sunglint is much larger than that over the non-glint areas and can exceed reflectance from thin clouds. Cloud detection over these regions is challenging for the EPIC instrument because of its limited spectral channels. One main region that is prone to error in cloud masking is the sunglint area over ocean surfaces. Inaccurate cloud masking is a great source of uncertainty. With the ability to observe the entire sunlit side of the Earth, EPIC data have become an important resource for studying cloud daily variability. 4SSAI/NASA Goddard Space Flight Center, Ocean Ecology Laboratory, Greenbelt, MD, United States.3JCET/Department of Physics, University of Maryland Baltimore County, Baltimore, MD, United States.2JCET/University of Maryland Baltimore County, Baltimore, MD, United States.1NASA Goddard Space Flight Center, Greenbelt, MD, United States.Dub has since than been widely understood as a stylistic crossing of musical and tonal quality of electronically produced or processed music, aswell as a specific musical aura that is caused by long reverbs, echo delay and differentiated sound effects and a reduction of the sonic texture and in addition, one of the reggae borrowed bass line in the center of the pieces, which is characterized by extreme low bass parts.Yaping Zhou 1,2* Yuekui Yang 1 Peng-Wang Zhai 3 Meng Gao 1,4 In the 1990s a correlation between dub-reggae and various popular styles of electronic dance music developed. In Vienna the regular Monday "Dub Club" established in the flex, and with the "Vienna Dubquake" an anchor point for the scene had been set up in 2008. In the early 90s, the spark of the roots reggae revival sprang also to Germany, which has since then developed a actively reggae and dub scene in Bavaria and cities such as Hamburg or Cologne. The creation of Jah Shaka's the point of reference for the roots reggae revival in Britains late 80s, with births of new Soundsystems (such as boom-Shacka-Lacka) and Dub-projects such as the Disciples or Alpha & Omega. and there is nothing better than the roots & culture tent, where there are reasonings, discussions, movies, exhibitions and much more. We have not just the music as in our mainfocus at this festival! We even try to deliver a message through that event. Between 19 Jah Shaka published ten Dub reggae LPs of his series Commandments of Dub. While in Jamaica, dancehall-reggae and later ragga music ruled in the 1980s, Jah Shaka a sound system operator and record producer in England further maintained and continued the roots reggae tradition. In the Mid 70s dub albums like King Tubbys Dubbing With The Observer were very successful in England. Since the early 1960s Jamaican music had, a high priority in the UK popular music scene. pioneers of this era include "Sir Coxsone" Dodd, Duke Reid and Prince Buster. Since the dances were very popular so quickly, the soundsystems dodged on free spaces, the so called Lawn.: at this time Selectors also started their own playing technique and thus to develop an individual sound. The first plate entertainers, then Soundman, today Selector called, organized dances or Bashment in so-called "Dancehalls". The first soundsystem formed in the early 1960s, when Jamaicas "folk music" experienced a strong development, and new music genres such as ska and rock steady emerged. The Rise & Shine Festival is the first Roots & Dub festival in Austria! The idea is to unite music and culture for two days in the original style.
