About ian_zhangty

  1. Dear all, I am now have some hour solar radiation data for each day: for example: 0 0 0 0 0 0 0 25 144 285 419 478 483 447 362 223 88 4 0 0 0 0 0 0 This is one day's records, and each number means each hour, I have 24 records for each day (as 24 hours in each day). You can see in the early morning and late night, the radiation is 0 due to sunset. Now I want to know the daily average solar radiation. So should I calculate the arithmetic mean with 0 or without zero? Personally, I think it might be the average without 0? But I cannot find any support from Internet. Appreciate to share your opinion with me. Thank you very much. Ian
