How do JPSS weather satellites achieve global coverage?

They orbit from pole to pole as Earth turns underneath.

  1. They use polar orbits ✔
  2. They hover over one city
  3. They circle the Moon

Why: JPSS satellites repeatedly cross from pole to pole while Earth rotates below. This changing path lets them observe the entire globe twice each day.

Huh, didn't know that: JPSS data help improve forecasts three to seven days before severe weather.

The dad joke
A polar satellite sees the world one strip at a time.
