This morning my Sky is not registering the drizzle that is falling. About .01" of rain fell according to conventional rain gauge but nothing on Sky. So it appears the Sky isn’t sensitive enough on low intensity rainfall but too sensitive with higher intensity rainfall giving totals 3 to 4 times higher than actual.
EDIT. As a follow-up, today’s rain event was a warm rain process-tropical type process with lots of small droplets. Sky reported 0.192" vs 0.34" rain gauge. This is the first time for me that Sky actually under reported a significant rain event since it is usually 3 to 4 times over for larger rain drop events.
