| description | The Korea Aerospace Research Institute (KARI) has collaborated with Jeollanamdo Agricultural Research & Extension Services and Chonnam National University to establish a ground observation tower for evaluating the value-added products (such as surface reflectance and Normalized Difference Vegetation Index) and improving algorithms of domestic development satellites (Korea Multi-Purpose Satellite-3, 3A and 7). The ground measurement tower, installed at the Jeollanamdo Naju ground observation site (NGOS), constantly observes surface hyperspectral reflectance and atmospheric information, providing the advantage of real-time algorithm validation improvement when satellite acquires images of the site. The NGOS operates hyperspectral radiometer equipment (6 types), meteorological observation equipment (5 types), sky radiometer (1 type), and eddy flux observation equipment (2 types), along with a web service for display and data processing. The ground observation site equipment that is being installed and operated can be utilized in various fields such as carbon circle, agriculture, environment, atmosphere and climate change, in addition to validation of satellite value-added products. This study aims to introduce KARI NGOS for user data sharing and highlight the characteristics of the measured data. |
