SST satellites
3
Introduce satellite Infrared vs Microwave cloud spatial resolution
Narrow and short phenomenon more details less errors
4
How to improve spatial resolution
MASER(microwave amplification by stimulated emission of radiation) amplifier pumping wave Stimulated emission Stimulated emission Incoming photon Amplifying wave Figure 1. stimulated emission’s principle
5
How to improve temporal resolution
Adjust satellite altitude Satellite’s speed & period eq. V= 𝐺 𝑀 𝐸 𝑅 = 2𝜋𝑅 𝑇 , T= 2𝜋𝑅 𝑉 LEO ranges 160km~2000km(160km altitude satellite = NS) V ≒ 7.79km/sec T ≒ 88 min(16 times per day) Revisit time shorter
6
How to improve temporal resolution
Is it possible 2513km of swath at NS? 2513km ≤ NS’s swath y = 0.225x - α = 77.32˚ l = aβ - β = 22.5˚ - γ = 77.20˚ 77.32˚(α) > 77.20˚(γ) Figure 2. At 160km Figure 3. For 2513km swath
7
Expectations for Massive Use in the Future!
conclusion Spatial resolution more less than 25km observation of smaller scale oceanic processes Temporal resolution about 15min difference(vs WINDSAT) Spatial resolution & Temporal resolution observe all of regions with or without cloud decreasing errors between the data Expectations for Massive Use in the Future!
