These Level 3 composites generated at global and regional scales using two distinct types of compositing algorithm. At the global scale, large (nominally 4.6km) sample sizes are used with each input Level 2 pixel accumulated into a geographic 'bin'. This is the standard form of compositing carried out where the output bin is much larger than the size of the input instrument samples. Unfortunately at higher scales, where the input and output sample sizes are comparable, the input samples overlap several cells of the output grid to a significant degree. If this is not taken into account then both the fine scale values and the overall product statistics are distorted (i.e. the final product is not flux conserving). \n\nFor the regional products, with nominal sample spacings of 1km or less, an area weighted, flux conserving compositing algorithm is used. This algorithm was developed by Tom McGlynn of NASA. \n\nThe HiProGen Level 3 Production system makes use of the Basic ENVISAT (A)ATSR and MERIS (BEAM) toolkit. Mathematically, different input data values are combined using a Maximum Likelihood, Arithmetic Mean or Min-Max algorithm. The Infoterra service uses the arithmetic mean algorithm for all Level 3 product generation.", "modified": "2014-09-28", "ob_ref": 7785 }, { "id": 7321, "key": "observation_collection.content.links", "value": "<div property=\"cedacat:links\">\r\n<div class=\"links\">Documentation and Links to further information and references</div>\r\n<p>\r\nFor more information about the technical specifications of the ISAR, please consort:\r\n</p><ul>\r\n<li><a href=\"http://www.isar.org.uk\">ISAR Page</a><a /></li><a>\r\n</a></ul><a>\r\n<p />\r\n<p>\r\nFurther information about the (A)ATSR Validation Campaign can be found in:\r\n</p></a><ul><a>\r\n</a><li><a /><a href=\"https://earth.esa.int/workshops/validation_12_02/aatsr/Meeting_Workshops.html\">(A)ATSR Validation Site</a></li>\r\n</ul>\r\n<p />\r\n</div>\r\n\r\n\r\n", "modified": "2016-06-28", "ob_ref": 7787 }, { "id": 7322, "key": "observation_collection.content.introduction", "value": "<div property=\"cedacat:introduction\">\r\n<div class=\"introduction\">Introduction</div>\r\n<p>\r\nThe prime objective of the (A)ATSR mission is to return accurate measurements of the global sea surface temperature.

The compromise takes the form of using either of two main operating modes - spatial and spectral modes - which reduce the data recording requirements.</p>\r\n</li><li>Spatial Mode & Default Bandsets:\r\n<p>Spatial mode records data from all 512 spatial dimension pixels, but from a limited number of programmable spectral bands (max. 18) by selection and summation of the 1.8 nm resolution detector elements. This provides an equivalent, spatially contiguous, multi-band data set to that recorded by the other airborne sensor - the Airborne Thematic Mapper (ATM). A spatial bandset can be formed from single detector elements or unique summations of two or more adjacent detector applications. elements located throughout the entire spectral range of the casi (400-915 nm). A single detector element cannot be summed into more than one spatial band, even if the spatial bands are adjacent. The number, locations and bandwidths of the different bands can be set up, according to the user application, to cover either broad spectrally different regions eg. blue, green, red, and near-infrared, or at precisely placed narrow wavelengths to measure specific phenomena eg. chlorophyll fluorescence, red-edge position, or atmospheric absorptions.</p>\r\n</li><li>Spectral Mode & Scene Recovery Channel:\r\n<p>In spectral mode the full spectral profile of 288 channels can be recorded, but from a limited number of look directions, or pixel positions, spread as a rake across the ground (max. 39). The 39 'tines' of this 'push-rake spectrometer' mode can be located with either 4, 8, 12 or 16 non-imaged pixels (look spacing) between each recorded spatial pixel, according to the user requirement; concentrating pixels together for high spatial resolution or spreading them out across the entire swath for good spatial coverage. Due to the missing spatial pixels it may sometimes be difficult to precisely locate the rake of spectral pixels within a scene. To offset this problem the Spectral Mode simultaneously produces a single full spatial band, formed from a single detector element, which is inherently co-registered with the separate look-directions. Using this Scene Recovery Channel (SRC) it is possible to locate the pixels positions of the spectral data within the scene. When selecting Spectral Mode for an airborne remote sensing mission the operator needs to program the casi with the spread of the push-rake, either 4, 8, 12 or 16 non- imaged pixels between the 'tines', and the channel wavelength (nm) for the SRC.</p>\r\n</li><li>Enhanced Spectral Mode\r\n<p>In the Enhanced Spectral Mode the full 3D data cube can be alternatively sliced into a single block of 101 adjacent spatial pixels imaged for all 288 spectral channels. This mode can be further extended into a series with increasing spatial coverage (more spatial pixels) at the expense of decreasing spectral resolution (fewer, wider channels). Each output band is formed by either a single detector element (101 x 288) or summations of adjacent detectors ie. summations of CCD row l+2, etc. or l+2+3, etc. thus maintaining a consistent integration time. The next table shows some typical examples of the look directions versus number of spectral channels, indicating the effect on frame rate and pixel resolution.</p>\r\n</li><li>Geometrically Corrected Data Products\r\n<p>Casi data acquired by the NERC Airborne Research and?Survey Facility from July 1994 can be geometrically registered to a map coordinate system using real-time measurements of aircraft attitude during project overflights.</p>\r\n<table align=\"center\">\r\n<tbody>\r\n<tr class=\"shadedarker\">\r\n<th>Look directions</th>\r\n<th>No. of spectral channels</th>\r\n<th>Spectral resolution (nm)</th>\r\n<th>Approximate frame rate (frames/sec)</th>\r\n<th>Spatial Resolution WxL (m)</th>\r\n<th>Altitude (m above ground level)</th></tr>\r\n<tr>\r\n<td class=\"data\">101</td>\r\n<td class=\"data\">101</td>\r\n<td class=\"data\">203</td>\r\n<td class=\"data\">303</td>\r\n<td class=\"data\">511</td>\r\n<td class=\"data\">3049</td></tr>\r\n<tr class=\"shade\">\r\n<td class=\"data\">288</td>\r\n<td class=\"data\">48</td>\r\n<td class=\"data\">144</td>\r\n<td class=\"data\">96</td>\r\n<td class=\"data\">48</td>\r\n<td class=\"data\">1000</td></tr>\r\n<tr>\r\n<td class=\"data\">1.8</td>\r\n<td class=\"data\">10.8</td>\r\n<td class=\"data\">3.6</td>\r\n<td class=\"data\">5.6</td>\r\n<td class=\"data\">10.8</td>\r\n<td class=\"data\">3049</td></tr>\r\n<tr class=\"shade\">\r\n<td class=\"data\">7</td>\r\n<td class=\"data\">38</td>\r\n<td class=\"data\">7</td>\r\n<td class=\"data\">7</td>\r\n<td class=\"data\">9</td>\r\n<td class=\"data\">3049</td></tr>\r\n<tr>\r\n<td class=\"data\">3.7 x 7.3</td>\r\n<td class=\"data\">1.2 x 1.2</td>\r\n<td class=\"data\">3.7 x 7.3</td>\r\n<td class=\"data\">3.7 x 7.3</td>\r\n<td class=\"data\">3.7 x 7.3</td>\r\n<td class=\"data\">3049</td></tr></tbody></table>\r\n<p align=\"center\"><strong>Table 2.</strong> Typical possible configuration in Enhanced Spectral Mode. <strong>Note:</strong> Aircraft speed over ground is assumed to be 100knots (51 m/s) for the above calculations.</p>\r\n<p>(However, both the Spectral and Enhanced Spectral Modes have a distinct drawback, since integration times are much longer than for Spatial Mode. This precludes the general use of these high data rate modes at low altitudes where fast integration times are required to maintain the squareness of pixels (pixel widths being smaller because of the low altitude). If this is not attainable at the altitude required, an aspect ratio (pixel length to width) of 2:1 or more may have to be selected by the operator).</p>\r\n</li><li>Full Frame Mode:\r\n<p>Full Frame Mode is generally only used during laboratory calibrations since the integration times (1-2 seconds) are too long to be used during airborne flights without tremendous smearing of the image.
