OpenET shows lower latency and 7‑day ET forecasting plans; Otter near operational for ET of applied water
Summary
OpenET reported provisional latencies (Landsat‑9: 1–3 days; Landsat‑8: 3–7 days), a low‑latency provisional feed and Otter development to compute effective precipitation and ET of applied water; the team plans to integrate new satellites and meteorological inputs and to offer near‑real‑time reporting for managers.
Forrest, a senior scientist at NASA Ames who works with the OpenET consortium, briefed the DMEC on advances in data latency, forecasting and the Otter system for calculating effective precipitation and ET of applied water. "For Landsat 9, within typically 1 to 3 days of satellite overpass; for Landsat 8 typically 3 to 7 days," he said when describing provisional data pathways, and he noted a separate archival (final) collection used for annual reporting.
OpenET is delivering multiple access…
