  • Representativenss probably dominated by time with water
  • He did linear interpolation of 3-hour to see what is required, and it implied very small times
  • NWP interpolates to 1 hour for observations, but sondes are already at the exact analysis times, so no interpolation of model?
  • Hamming implies they must use more channels if they can't utilize the low noise of CrIS
