Idea is to produce observation averages around fixed time intervals in a day (like 3,6,9,12,15,18 and 21z) using 1 hour windows. However, I am getting fill values in result, although valid observations are available at those times. Both input and ncl code is attached. Any help is appreciated.</div><div>Thank you</div><div>Debasish.</div></div>
