VIIRS/JPSS1 Moderate Resolution 6 Min L1B Swath 750m NRT

The VIIRS/JPSS1 Moderate Resolution 6-Min L1B Swath 750m Near Real Time (NRT), short-name VJ102MOD_NRT is one of VIIRS Level 1 and Level 2 swath products that is generated from the processing of 6 minutes of VIIRS data acquired during the JPSS1 satellite overpass. The VJ102MOD_NRT is VIIRS L1B calibrated radiances product that comprise sixteen moderate-resolution or M-bands, which have a spatial resolution of 750-meters at nadir. These M-bands comprise eleven reflective solar bands (RSB) and five thermal emissive bands (TEB). Each of the M-bands has 16 detectors in the along-track direction with 16 rows of pixels per scan that provide a 750-m resolution. Ranging in wavelengths from 0.402 micron to 12.49 micron, the M-bands are sensitive to visible, near-, shortwave-, mediumwave-, and longwave-infrared wavelengths. Derived from the NASA VIIRS L1A raw radiances, this product includes calibrated and geolocated radiance and reflectance data, quality flags, and granule- and collection-level metadata. In contrast to a MODIS L1B product, which temporally spans 5 minutes, the VIIRS L1B calibrated radiances product contains a nominal temporal duration of 6 minutes.

The spatial resolution of the instrument at viewing nadir is approximately 750 m for the Moderate-resolution and Day/Night Bands, and 375 m for the Imagery bands.

VJ102MOD_NRT，简称VIIRS/JPSS1中分辨率6分钟L1B扫描带750米近实时（NRT），系VIIRS一级和二级扫描产品之一，由JPSS1卫星过境期间采集的VIIRS数据经过6分钟的处理生成。该产品为VIIRS L1B校准辐射亮度产品，包含十六个中分辨率或M波段，在视场下方具有750米的空间分辨率。这些M波段包括十一个反射太阳波段（RSB）和五个热辐射波段（TEB）。每个M波段在沿轨迹方向具有16个探测器，每扫描一行包含16个像素，提供750米的分辨率。波长范围从0.402微米至12.49微米，M波段对可见光、近红外、短波、中波和长波红外波长敏感。该产品基于NASA VIIRS L1A原始辐射亮度数据，包含校准和地理定位的辐射亮度与反射率数据、质量标志以及粒度和集合级元数据。与时间跨度为5分钟的MODIS L1B产品相比，VIIRS L1B校准辐射亮度产品的标准时间持续为6分钟。仪器在视场下方的空间分辨率对于中分辨率和日夜波段约为750米，对于图像波段约为375米。
