1000W m^2 is actualy closer to high noon at Kansas on a fully clear day (this is equivalent to 2,000 umol/cm^2/s-1) Equatorial solar irradiance is actually higher (closer to 1,050W/m^2) because the equator is just a bit closer to the sun.

No, no, no. Equatorial is higher because the sun is more directly overhead on average than in Kansas.

That's not how the inverse square law works for photon flux density.
