MASTER: Tropical Composition, Cloud and Climate Coupling Campaign, 2007

This dataset includes Level 1B (L1B) and Level 2 (L2) data products from the MODIS/ASTER Airborne Simulator (MASTER) instrument. The spectral data were collected during seven flights aboard a NASA ER-2 aircraft over California, Nevada, Central America, and eastern Pacific Ocean from 2007-07-29 to 2007-08-18. This deployment supported the Tropical Composition, Cloud and Climate Coupling Campaign (TC4), which investigated the atmospheric structure, properties, and processes in the Eastern Pacific Tropics. Data products include L1B georeferenced multispectral imagery of calibrated radiance in 50 bands covering wavelengths of 0.460 to 12.879 micrometers at approximately 50-meter spatial resolution. Derived L2 data products are emissivity in 5 bands in thermal infrared range (8.58 to 12.13 micrometers) and land surface temperature. The L1B file format is HDF-4, and L2 products are provided in ENVI and KMZ formats. In addition, the dataset includes flight paths, spectral band information, instrument configuration, ancillary notes, and summary information for each flight, and browse images derived from each L1B data file.

本数据集收录了MODIS/ASTER机载模拟器（MASTER）仪器收集的L1B（一级B）和L2（二级）数据产品。光谱数据于2007年7月29日至2007年8月18日间，在NASA ER-2飞机上进行的七次飞行任务中，对美国加利福尼亚州、内华达州、中美洲及东太平洋海域进行采集。此次部署旨在支持热带组成、云层与气候耦合活动（TC4），旨在探究东太平洋热带大气结构、特性及其过程。数据产品包括覆盖0.460至12.879微米波长的50波段校准辐射度的大地参照多光谱影像，空间分辨率为约50米。派生出的L2数据产品包括5个波段的发射率（热红外范围8.58至12.13微米）及地表温度。L1B文件格式为HDF-4，而L2产品则提供为ENVI和KMZ格式。此外，该数据集还包括飞行路径、光谱波段信息、仪器配置、辅助注释以及每架次飞行的摘要信息，并附有由每个L1B数据文件派生出的浏览图像。
