Description:

Abstract:

AIRS/Aqua Level 3 pentad quantization product in physical units (AIRS Only). The quantization products (QP) are distributional summaries derived from the Level-2 standard retrieval products (of swath type) to provide a more comprehensive set of statistical summaries than the traditional means and standard deviation. The QP products combine the Level 2 standard data parameters over grid cells of 5 x 5 deg spatial extent for temporal periods of five days. Pentads always start on the 1st, 6th, 11th, 16th, 21st, and 26th days of the month and may contain as few as 3 days of data or as much as 6 days. They preserve the multivariate distributional features of the original data and so provide a compressed data set that more accurately describes the disparate atmospheric states that is in the original Level-2 swath data set. The geophysical parameters are: Air Temperature and Water Vapor profiles (11 levels/layers), Cloud fraction (vertical distribution). (The Shortname for this product is AIRS3QP5)

Attribute_Accuracy_Report:

The L3Q products combine the Level 2 standard data parameters over grid cells of 5 x 5 deg spatial extent for temporal periods of five days and one month. The report for each grid cell provides a number of representative values and their associated weights. The sample of lower level data points with the same representative is called a “cluster”, and its representative is the “cluster mean”. Cluster membership is determined by assigning lower level data points to clusters so that that the errors between original values and their representatives are minimized. This constraint prevents the creation of single-data-point clusters. As a general rule, Level 2 retrieved quantities whose quality indicators are “best” (=0) or “good” (=1) are included in the data that generate the L3Q product. Users MUST read information contained within the two documents below to avoid misuse of the L3Q products in their research.
