Sentinel-1 radar data acquisition for the composite image occurred in June 2026.
As part of the Copernicus Sentinel-1 mission, radar images were captured to monitor environmental changes. The composite image in question was formed by combining three separate radar acquisitions taken two months apart between February and June 2026.
In this composite, the data acquired in June 2026 was represented by the blue colour channel. These radar images serve tools for agriculture and environmental monitoring, such as tracking soil moisture, seasonal crop growth, and wetland health.

Sentinel-1 radar data acquisition for the composite image occurred in April 2026.
As part of a composite imaging process, the Copernicus Sentinel-1 mission performed a radar data acquisition in April 2026. This acquisition represents the middle stage of a sequence that includes observations taken two months apart from February to June 2026.
In the resulting composite image, the data from April 2026 is represented by the green colour channel. This specific period is used to identify vegetation that sprouted, grew densest, or experienced higher moisture levels during that month.
