NISAR卫星在2026年1月拍摄了路易斯安那州三角洲的详细雷达图像,显示尽管云层覆盖,但城市、河流和湿地。 The NISAR satellite captured detailed radar images of Louisiana’s Delta in January 2026, showing cities, rivers, and wetlands despite cloud cover.

美国航天局-ISRO NISAR卫星于2025年7月发射,捕捉了路易斯安那州密西西比河三角洲的高分辨率雷达图像,穿透云层以揭示新奥尔良、巴顿红色、密西西比河、庞查特雷恩湖和周围景观。 The NASA-ISRO NISAR satellite, launched in July 2025, has captured a high-resolution radar image of Louisiana’s Mississippi River Delta, penetrating cloud cover to reveal New Orleans, Baton Rouge, the Mississippi River, Lake Pontchartrain, and surrounding landscapes. 特派团利用L波段和S波段双重雷达系统,对土地变化,包括湿地丧失和沉降情况进行详细的全天候观测,这对救灾和环境监测至关重要。 Using dual radar systems—L-band and S-band—the mission provides detailed, all-weather observations of land changes, including wetland loss and subsidence, crucial for disaster response and environmental monitoring. 该图像于2026年1月发布,展示了39公里长的庞查特雷湖高速公路和植被健康变化等特征,数据将于2月底通过阿拉斯加卫星设施公开提供。 The image, released in January 2026, shows features like the 39-kilometer Lake Pontchartrain Causeway and variations in vegetation health, with data to be publicly available via the Alaska Satellite Facility in late February.
