From: Two origins of the winter subsidence in and around the Arabian Peninsula
(a) We selected three points representing the Persian Gulf, inland, and the Red Sea. (b) Change in equivalent water thickness from GRACE and GRACE-FO mascon solution released from UTCSR. Vertical grid lines indicate year boundaries. Best-fit seasonal (annual and semiannual) changes together with secular changes expressed with quadratic functions are added. Oceanic points show strong seasonal signatures but little secular trends. On the other hand, the inland point shows little seasonal variations but a significant negative trend.
