MASTER: Airborne Science, Southwest US, June, 2011

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 6 flights aboard a NASA ER-2 aircraft over southwestern U.S. and northern Mexico, from 2011-06-08 to 2011-06-20. The purposes of these flights include collecting data for wildfire mapping, airborne science initiatives, and calibration data for AVIRIS. This deployment was coordinated by NASA's Dryden Flight Research Center (DRFC), renamed Armstrong Flight Research Center in 2014, located in Edwards, California. 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 the flight path, spectral band information, instrument configuration, ancillary notes, and summary information for each flight, and browse images derived from each L1B data file.

本数据集汇集了来自MODIS/ASTER航空模拟器（MASTER）仪器的Level 1B（L1B）和Level 2（L2）数据产品。该光谱数据是在2011年6月8日至2011年6月20日期间，搭载NASA ER-2飞机，在美国西南部和墨西哥北部进行的6次飞行任务中采集的，空间分辨率为约50米，覆盖了从0.460至12.879微米的50个波段，经过校准的光辐射数据。此次飞行的目的包括收集用于森林火灾制图、航空科学项目以及AVIRIS校准数据。该部署由NASA德赖登飞行研究中心（DRFC）协调，于2014年更名为阿姆斯特朗飞行研究中心，位于加利福尼亚州爱德华兹。数据产品包括50米空间分辨率的校准辐射的L1B地理参照多光谱影像，以及在热红外波段（8.58至12.13微米）内的5个波段的发射率以及地表温度的派生L2数据产品。L1B文件格式为HDF-4，L2产品以ENVI和KMZ格式提供。此外，数据集还包括飞行路径、光谱波段信息、仪器配置、辅助说明以及每架次飞行的总结信息，以及由每个L1B数据文件派生的浏览图像。
