Book Description
This report describes the work done for the Starfire Optical Range, Kirtland Air Force Base under Contract N00014-01-D-043 DO #11, between 02 September 2004 and 30 April 2006. This work relates to the Air Force's need to characterize the cloud distribution during day and night, for a variety of applications, including support of research into impact of clouds on laser communication and support of satellite tracking. This contract followed Contract N00014-01-D-0043 DO #4, which will be discussed in Section 2, and is documented in Shields et al 2007, Technical Note 271. Under this contract, we began preparing Whole Sky Imager systems for field experiments in support of program goals, adapting the software and refurbishing the hardware. Significant progress was made both in the related cloud algorithms and in methods to assess their accuracy. A related contract was funded through Boeing during 31 January 2005 - 30 November 2005. The tasks completed under that contract are closely related to these tasks, and will also be reported here. In particular, early portions of the night algorithm work reported in Section 7, and early portions of the hardware and software refurbishment were completed partly under the ONR contract and partly under the Boeing contract. The work under this Boeing contract was finished in May 2005. A follow-on contract, ONR N00014-0l-D-0043 DO #13 was funded on 20 April 2006. The work under DO #13 will be reported under a separate report upon completion of the contract.

Book Description
Solar Energy Forecasting and Resource Assessment is a vital text for solar energy professionals, addressing a critical gap in the core literature of the field. As major barriers to solar energy implementation, such as materials cost and low conversion efficiency, continue to fall, issues of intermittency and reliability have come to the fore. Scrutiny from solar project developers and their financiers on the accuracy of long-term resource projections and grid operators' concerns about variable short-term power generation have made the field of solar forecasting and resource assessment pivotally important. This volume provides an authoritative voice on the topic, incorporating contributions from an internationally recognized group of top authors from both industry and academia, focused on providing information from underlying scientific fundamentals to practical applications and emphasizing the latest technological developments driving this discipline forward. - The only reference dedicated to forecasting and assessing solar resources enables a complete understanding of the state of the art from the world's most renowned experts. - Demonstrates how to derive reliable data on solar resource availability and variability at specific locations to support accurate prediction of solar plant performance and attendant financial analysis. - Provides cutting-edge information on recent advances in solar forecasting through monitoring, satellite and ground remote sensing, and numerical weather prediction.

Book Description
The book describes — How to shoot and process still image “nightscapes” – images of landscapes taken at night by the light of the Moon or stars … and … How to shoot and assemble time-lapse movies of the stars and Milky Way turning above Earthly scenes, all using DSLR cameras. The 400-page multi-touch book includes — 50 embedded HD videos (no internet connection required) demonstrating time-lapse techniques. 60 multi-page tutorials with step-by-step instructions of how to use software: Adobe Bridge, Adobe Camera Raw, Photoshop, Lightroom, LRTimelapse, Advanced Stacker Actions, StarStaX, Panolapse, Sequence, GBTimelapse, and more. Numerous Photo 101 sections explaining the basic concepts of photography and video production (f-stops, ISOs, file types, aspect ratios, frame rates, compression, etc.). Numerous Astronomy 101 sections explaining the basics of how the sky works (how the sky moves, where the Moon can be found, when the Milky Way can be seen, when and where to see auroras). Reviews of gear – I don’t just mention that specialized gear exists, I illustrate in detail how to use popular units such as the Time-Lapse+, Michron, and TriggerTrap intervalometers, and the All-View mount, Radian, Mindarin Astro, eMotimo, and Dynamic Perception motion-control units, with comments on what’s good – and not so good – to use. You’ll learn — What are the best cameras and lenses to buy (cropped vs. full-frame, Canon vs. Nikon, manual vs. automatic lenses, zooms vs. primes). How to set your cameras and lenses for maximum detail and minimum noise (following the mantra of “exposing to the right” and using dark frames). How to shoot auroras, conjunctions, satellites, comets, and meteor showers. How to shoot nightscapes lit only by moonlit, and how to determine where the Moon will be to plan a shoot. How to shoot & stitch panoramas of the night sky and Milky Way, using Photoshop and PTGui software. How to shoot tracked long exposures of the Milky Way using camera trackers such as the iOptron Star Tracker and Sky-Watcher Star Adventurer. How to develop Raw files, the essential first step to great images and movies. How to process nightscape stills using techniques such as compositing multiple exposures, masking ground and sky, and using non-destructive adjustment layers and smart filters. How to shoot and stack star trail images made of hundreds of frames. How to assemble time-lapse movies from those same hundreds of frames. How to plan a time-lapse shoot and calculate the best balance of exposure time vs. frame count vs. length of shoot, and recommended apps to use. How to process hundreds of frames using Adobe Camera Raw, Bridge, Photoshop, and Lightroom. How to shoot and process advanced “Holy Grail” time-lapse transitions from day to night. How to shoot motion-control sequences using specialized dolly and pan/tilt devices. How to use time-lapse processing tools such as LRTimelapse, Panolapse, Sequence, and Advanced Stacker Actions. What can go wrong and how best to avoid problems in the field.
