TCSP ER-2 MODIS AIRBORNE SIMULATOR (MAS) V1

The TCSP ER-2 MODIS Airborne Simulator (MAS) dataset was collected by a MODIS Airborne Simulator (MAS), which is a multi-spectral line-scanner system that acquires image data in 50 spectral bands over wavelengths ranging from 0.46 to 14.3 microns. Flown on the ER-2 aircraft at an operating altitude of 19.8 km (65,000 ft.), it produces nominal pixel sizes of 50 meters. MAS includes nine spectral bands in the visible/near infrared, 16 bands in the shortwave infrared, 16 bands in the mid-wave infrared, and nine bands in the thermal infrared regions of the spectrum. The instrument field-of-view is 86 degrees, with an IFOV of 2.5 mrad. The MAS collected calibrated multi-spectral imagery from the ER-2 aircraft during the TCSP experiment. The MAS was developed by NASA primarily to validate L1B and L2 science products from the EOS satellite program. MAS data enables (1) the mapping of sub-pixel variation within the co-incident footprints of many orbital instruments (e.g. MODIS, AIRS, HIRS, AVHRR, GOES) in the visible and thermal infrared spectral regions and (2) the estimation of surface, aerosol, and cloud properties at 50 meter spatial resolution. The TCSP mission collected data for research and documentation of cyclogenesis, the interaction of temperature, humidity, precipitation, wind and air pressure that creates ideal birthing conditions for tropical storms, hurricanes and related phenomena. The goal of this mission was to help us better understand how hurricanes and other tropical storms are formed and intensify.

TCSP ER-2 MODIS 机载模拟器（MAS）数据集由 MODIS 机载模拟器（MAS）收集而成，MAS是一种多光谱线扫描系统，能够在0.46至14.3微米波长范围内获取50个光谱波段的数据。该模拟器搭载于ER-2飞机上，飞行高度为19.8公里（65,000英尺），生成的标准像素大小为50米。MAS包括可见光/近红外光谱区域的9个光谱波段，短波红外光谱区域的16个波段，中波红外光谱区域的16个波段，以及热红外光谱区域的9个波段。仪器的视场角为86度，IFOV（瞬时视场角）为2.5毫弧度。MAS在TCSP实验期间从ER-2飞机上收集了校准后的多光谱图像。NASA主要开发MAS以验证EOS卫星计划中的L1B和L2科学产品。MAS数据使得（1）能够在可见光和热红外光谱区域内，对多个轨道仪器（例如MODIS、AIRS、HIRS、AVHRR、GOES）的重叠足迹内的亚像素变化进行映射；（2）以50米的空间分辨率估计地表、气溶胶和云的特性。TCSP任务收集的数据用于研究并记录气旋生成过程，包括温度、湿度、降水、风和气压的相互作用，这些因素创造了热带风暴、飓风及相关现象的理想孕育条件。此次任务的目标是帮助我们更好地理解飓风和其他热带风暴的形成和增强机制。
