sample size requirement when do kriging interpolation
Dear Jessie You can do kriging on 27 points. The difficulty comes from estimating the variogram with only 27 sites. Some studies have approached this by using measurements at multiple points in time instead. I give some references below. I think Edzer (Pebesma) also used this approach, but I can't remember the paper right now. I hope this helps. Nick Y. Zhang, N.A.S. Hamm, N. Meratnia, A. Stein, M. van de Voort & P.J.M.

Hi all, I'm doing the kriging interpolation for the daily concentration of PM10. I only have 27 monitoring sites every day. I want to know if it is appropriate to do kriging interpolation. Do you have some good advices?
