Heavy Rains in Northern Cali
| Title |
Heavy Rains in Northern California |
| Description |
A powerful storm system brought high winds and heavy downpours to parts of central and northern California, causing localized flooding and knocking out power in the San Francisco Bay area. The weather station on Angel Island in San Francisco Bay measured strong wind gusts, including one that peaked at 156 kilometers per hour (98 miles per hour). This storm system was brought in by a powerful subtropical jet steam, which provided moisture and strong upper-level winds. The system spawned thunderstorms that brought lightning and sizeable hail around Sacramento. Coastal regions also measured heavy rainfall, though there was no widespread flooding there. The Tropical Rainfall Measuring Mission (TRMM) monitors rainfall based on a near-real-time, Multi-satellite Precipitation Analysis (MPA) at NASA's Goddard Space Flight Center. This image shows MPA rainfall totals for the central and northern West Coast from February 22 to March 1, 2006. The highest rainfall totals for the period are around 120 millimeters, about 5 inches, shown in red. These rainfall amounts occur along the western slopes of the coastal range, in the Klamath Mountains near the border with Oregon, and over the northern Sierra Nevada on the downwind side of the Sacramento Valley. The mountains forced moisture from the humid air rising over the slopes. MPA rainfall totals for the San Francisco Bay area are rather light, while the areas around Sacramento received a little over 70 millimeters, about 3 inches, shown in the brighter greens. The TRMM satellite was launched into service in November of 1997. It was engineered to measure rainfall over the global Tropics using both passive and active sensors, including the first and only precipitation radar in space. TRMM is a joint mission between NASA and the Japanese space agency, JAXA. Image produced by Hal Pierce (SSAI/NASA GSFC) and caption by Steve Lang (SSAI/NASA GSFC). |

Levee Break Floods Central California |
| Description |
A broken levee near the San Joaquim-Sacramento River delta flooded nearly 12,000 acres of farmland in Central California on June 3, 2004. According to news reports, about 300 people were evacuated from the flood region. An intricate series of levees and canals channel the fresh water from melting snow in the Sierra Nevada Mountains to the farmland in California?s Central Valley. A break on one levy can affect the distribution of water to others. In this case, up to one million acres of farmland may receive less water during June, the typical peak irrigation month. Additionally, the change in the water level could draw salty water from the San Francisco Bay into the freshwater delta, threatening to contaminate the drinking water of many of California?s cities. The levee that broke is about 20 miles (32 kilometers) west of Stockton, and the breach allowed water from the Middle River to create a vast lake, visible in imagery taken by the Moderate Resolution Imaging Spectroradiometer [ http://modis.gsfc.nasa.gov ] (MODIS) on NASA?s Aqua [ http://aqua.nasa.gov/ ] satellite on June 5. A false-color MODIS image taken on June 2 shows the water network before the levee broke. In both scenes, tan and bright green squares are agricultural fields. The high-resolution images provided above are at MODIS? maximum resolution. Both the June 5 [ http://rapidfire.sci.gsfc.nasa.gov/gallery/?2004157-0605/California.A2004157.2110.721 ] and June 2 [ http://rapidfire.sci.gsfc.nasa.gov/gallery/?2004154-0602/California.A2004154.1900.721 ] images are available in additional resolutions.

Northern California Floods
| Title |
Northern California Floods |
| Description |
Northern California ushered in 2006 with a series of major storms that inundated the area and left many towns awash in water, mud, and debris. According to a report from the USATODAY.com Website, at least two levees in the Sacramento-San Joaquin Delta region were unable to handle the rising waters and strong winds, and residents nearby evacuated as the water-control structures began leaking. In the wine-country town of Napa perhaps as many as 1,000 homes were flooded along with thousands of acres of rural and agricultural land. The governor declared several counties in the region flood disaster areas. This pair of images shows flooding in the Sacramento-San Joaquin Valley region inland of San Francisco Bay. The image on the left was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite on December 10, 2005, while the image at right was captured on January 4, 2006, just days after the severe storms passed through. Dark blue pools of water swamp far larger areas of ground in January than they did in December. The Sacramento River is very wide and turbid, the sediment in the water is reflective and gives the river its lighter blue appearance. Flood control channels alongside the river help carry the additional flows. The northern reaches of San Francisco Bay are also bright with sediment, which may be a mixture of river run-off and churning of the Bay by storm winds. Vegetation is bright green, snow in the Sierra Nevada Mountains is bright blue (upper right), and bare or sparsely vegetated ground appears pinkish or reddish tan. The rain-producing storms that passed through the state became blizzards as they crossed the mountains. A wider-area image [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?USA1/2006004/USA1.2006004.aqua.721 ] produced by the MODIS Rapid Response Team shows snow cover on the Sierra Nevada Mountains and across the Great Basin.

Fires in California
| Title |
Fires in California |
| Description |
The combined smoke from the Freds and Power Fires in northern California southwest of Lake Tahoe was filling in the northern end of the Sacramento Valley on October 14, 2004. This image was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA?s Aqua satellite in the afternoon, when smoke had become so thick the actively burning areas of the fire that MODIS on the Terra satellite detected during its morning overpass [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?AERONET_Fresno/2004288/AERONET_Fresno.2004288.terra ] could no longer be picked up. Southwest of Lake Tahoe, the northernmost band of thick smoke is associated with the Freds Fire, while the central and southern ones are associated with the Power Fire. The smoke has risen far enough into the air to be casting a shadow onto another, thinner layer of smoke below. Smoke nestles into the ravines and canyons of the many rivers that run off the Sierra Nevada Mountains, causing them to stand out from the forested terrain. Other landmarks in the scene include San Francisco Bay, along the bottom edge to the left of center, Clear Lake, in the upper left quadrant, the southern end of Nevada?s Pyramid Lake, at upper right, and the gray-colored rock of Yosemite National Park, to the west of Mono Lake at bottom right. A small fire was detected by MODIS in that area and is outlined in red. NASA image courtesy the MODIS Rapid Response Team, NASA-Goddard Space Flight Center |

Perspective View with Landsat Overlay, Sacramento, Calif. |
| Original Caption Released with Image |
California's state capitol, Sacramento, can be seen clustered along the American and Sacramento Rivers in this computer-generated perspective viewed from the west. Folsom Lake is in the center and the Sierra Nevada is above, with the edge of Lake Tahoe just visible at top center. This 3-D perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM) and an enhanced color Landsat 5satellite image. Topographic expression is exaggerated two times. Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter (98-foot) resolution of most Landsat images and will substantially help in analyzing the large and growing Landsat image archive. Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR)that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect 3-D measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter (approximately 200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., for NASA's Earth Science Enterprise, Washington, D.C. Size: scale varies in this perspective image Location: 38.6 deg. North lat., 121.3 deg. West lon. Orientation: looking east Image Data: Landsat Bands 3, 2, 1 as red, green, blue, respectively Original Data Resolution: SRTM 1 arcsecond (30 meters or 98 feet), Thematic Mapper 1 arcsecond (30 meters or 98 feet) Date Acquired: February 2000 (SRTM) |

Northern California near San
| Title |
Northern California near San Francisco |
| Description |
A part of northern California centered near San Francisco Bay (38.0N, 122.0W) photographed at 3 p.m. January 1, 1974, from the Skylab space station in Earth orbit. This near vertical view encompasses the coastline from Monteray Bay (right) to about 50 miles north of Point Reyes (left) and includes, from bottom to top, San Francisco Bay (center), Sacramento Valley (left center), San Joaquin Valley (right center), and the snow-covered Sierra Nevada. Afternoon shadows sharply delineate a valley which parallels San Francisco Bay, crosses Point Reyes, and lies between the Bay and the Pacific coastline. This valley marks the location of the San Andreas Fault. Forces acting on the crust are causing the land west (bottom) of the fault line to move north relative to land on the east side. Agricultural areas in the Sacramento and San Joaquin Valleys are indicated by the tan areas which are easily discerned in contrast to the green-gray background. |

Sierra Nevada Mountain Range as seen from STS-58 |
| Description |
The Sierra Nevada Mountain Range can be seen in this north-looking high oblique view taken in October, 1993, by the STS-58 crew. Visible in the view to the west of the Sierra Nevada are the San Joaquin and Sacramento Valleys of central California. The San Francisco/Oakland Bay Area can be seen to the west of the valley at the extreme left of the photograph. To the east or right of the Sierra Nevada, the basin and Range Region of central and northern Nevada is visible. Mono Lake, Lake Tahoe and Pyramid lake are also visible in this scene. The long northwest/southeast trending Walker Lane Shear Zone, which lies just to the east (right) of the Sierra Nevada is also visible. Near the top of the view (near the horizon), the snow covered volcanic peak Mount Shasta can be seen. |
