MASTER: HyspIRI Airborne Campaign, California, Summer 2017

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 as part of the Hyperspectral Infrared Imager (HyspIRI) airborne campaign during 9 flights aboard a NASA ER-2 aircraft over southern California and western Nevada, U.S., from 2017-06-07 to 2017-06-28. Two flights on 2017-06-26 and 2017-06-28 were flown jointly for the Student Airborne Research Program (SARP). SARP was an eight-week summer program for junior and senior undergraduate students to acquire hands-on research experience in all aspects of a scientific campaign using airborne science laboratories. 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.

本数据集包含来自MODIS/ASTER机载模拟器（MASTER）仪器的Level 1B（L1B）和Level 2（L2）数据产品。光谱数据作为Hyperspectral Infrared Imager（HyspIRI）机载观测活动的一部分被收集，该活动于2017年6月7日至2017年6月28日在美国加利福尼亚州南部和内华达州西部，搭载NASA ER-2飞机进行，共计9次飞行。其中，2017年6月26日和2017年6月28日的两次飞行由学生机载研究计划（SARP）联合执行。SARP是一项为期八周的暑期项目，旨在为大学本科生提供亲身体验科学观测活动的各个方面，包括使用机载科学实验室的研究经验。数据产品包括经地理编码的50波段校准辐射的多光谱影像，覆盖波长范围从0.460至12.879微米，空间分辨率约为50米。派生出的L2数据产品包括5个波段的热红外范围（8.58至12.13微米）的发射率和地表温度。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、辅助说明以及每次飞行的总结信息，以及从每个L1B数据文件派生出的浏览图像。
