This dataset includes land and sea ice mask information adapted from the AVHRR Pathfinder sea surface temperature (SST) v5.0 and the Optimally Interpolated SST version 2 data sets, respectively. Additionally, near shore pixels originally contaminated by backscatter from land have been filled by several methods, including simple median filling, an inverse-distance weighted mean, and an objective analysis technique that considers the spatial structure of the wind speed data. The gap filling methods and QuikSCAT wind speed data were then evaluated by comparing with in situ wind speed measurements taken from near shore and open ocean buoys and marine weather stations. These data are in .HDF format identified by Julian date.

QuikSCAT was a "quick recovery" mission replacing the NASA Scatterometer (NSCAT), which failed prematurely in June 1997. QuikSCAT exceeded design expectations and continued to operate for over a decade before a bearing failure on its antenna motor ended QuikSCAT's capabilities to determine useful surface wind information on 23 November 2009. The QuikSCAT geophysical data record spans from 19 July 1999 to 21 November 2009. The SeaWinds instrument on the QuikSCAT satellite measured global marine winds. However, microwave backscatter from land and ice limited the coverage and utility of QuikSCAT wind speed measurements near the coast and at high latitudes. This QuikSCAT weekly wind speed dataset was developed at the NOAA National Oceanographic Data Center (now part of the NOAA National Centers for Environmental Information) to address limitations of the data.

NOAA National Centers for Environmental Information custodian AVHRR-2 AVHRR-2 Advanced Very High Resolution Radiometer-2 The AVHRR-2 is a multi purpose imaging instrument used for global measurement of cloud cover, sea surface temperature, ice, snow and vegetation cover and characteristics. This instrument was initially carried on NOAA-7 (launched June 1981) and was last flown on NOAA-14 which was decommissioned in 2005. This 5-channel radiometer covering 2 visible and 3 thermal infrared between 0.63 and 12.0 micrometers, has an instantaneous footprint of 1.1 km at the sub satellite point. Additional Information: https://nwpsaf.eu/deliverables/aapp/avhrr_2.html AVHRR-3 AVHRR-3 Advanced Very High Resolution Radiometer-3 The AVHRR-3 is a six channel scanning radiometer providing 3 solar channels in the visible-near infrared region and 3 thermal infrared channels. The AVHRR-3 has two one-micrometer wide channels between 10.3 and 12.5 micrometers. This latest version of AVHRR was first carried on NOAA-15 launched in May 1998 and subsequently in all current NOAA and MetOp platforms. Measuring the same view, this array of diverse wavelengths, after processing, permits multi spectral analysis for more precisely defining hydrologic, oceanographic, and meteorological parameters. Comparison of data from two channels is often used to observe features or measure various environmental parameters. The three channels operating entirely within the infrared band are used to detect the heat radiation from and hence, the temperature of land, water, sea surfaces, and the clouds above them.

The SeaWinds scatterometer is a microwave radar designed specifically to measure ocean near-surface wind speed and direction. A SeaWinds scatterometer was deployed on NASA's QuikSCAT mission in 1999. The SeaWinds scatterometer consists of three major parts: the Electronics Subsystem (SES), the Antenna Subsystem (SAS), and the Command and Data Subsystem (CDS). The Electronics Subsystem is the heart of the scatterometer and it contains a transmitter, receiver and digital signal processor. It generates and sends high radio frequency (RF) waves to the antenna. The antenna transmits the signal to the Earth's surface as energy pulses. When the pulses hit the surface of the ocean it causes a scattering affect referred to as backscatter. A rough ocean surface returns a stronger signal because the waves reflect more of the radar energy back toward the scatterometer antenna. A smooth ocean surface returns a weaker signal because less of the energy is reflected. The echo or backscatter is routed by the antenna to the SES through waveguides (rectangular metal pipes that guide RF energy waves from one point to another). The SES then converts the signals into digital form for data processing. The CDS is essentially a computer housing the software that allows the instrument to operate. It provides the link between the command center on the ground, the spacecraft and the scatterometer. It controls the overall operation of the instrument, including the timing of each transmitted pulse and collects all the information necessary to transform the received echoes into wind measurements at a specific location on Earth. To locate the precise position on Earth at which the echo was taken, the CDS collects (for each pulse) the antenna rotational position, spacecraft time, and an estimate of the spacecraft position. The CDS also collects instrument temperature, operating voltages and currents, so that the overall health of the instrument can be monitored. It is through the CDS that the other two subsystems receive the commands that control all of their functions. SeaWinds Scatterometer Layout: The SAS consists of a one-meter parabolic reflector antenna mounted to a spin activator assembly, which causes the reflector to rotate at 18 Rpm's (revolutions per minute). The activator assembly provides very accurate spin control and precise position or pointing information to the CDS. Optical encoders, glass disks with small patterns printed on the surface, tell the CDS exactly where the antenna is pointing to about 10/1000 of a degree. The antenna spins at a very precise rate, and emits two beams about 6 degrees apart, each consisting of a continuous stream of pulses. The two beams are necessary to achieve accurate wind direction measurements. The pointing of these beams is precisely calibrated before launch so that the echoes may be accurately located on the ground from space. Data derived from ocean scatterometers is vital to scientists in the their studies of air-sea interaction and ocean circulation, and their effects on weather patterns and global climate. These data are also useful in the study of unusual weather phenomena such as El Niño, the long-term effects of deforestation on our rain forests, and changes in the sea-ice masses around the polar regions. Scatterometer data, with wide swath coverage, have been shown to significantly improve the forecast accuracy of these models.
