The Voluntary Observing Ship (VOS) Scheme

Abstract: The Voluntary Observing Ships (VOS) Scheme is an observing program for marine meteorology, continuing a record extending back centuries. VOS are an important component of the surface observing system, providing air and sea surface temperatures, humidity, pressure, wind speed and direction, cloud cover, waves, ice and weather data. Observational metadata allow biases to be diagnosed and corrected.Despite its importance, the Scheme faces challenges. Observation numbers have declined as more data from satellites … Show more

“…Another intriguing question is whether PBQC is still feasible if some secret is shared by authorized receiver and reference stations, instead of communicating all information through public channels. Very recently, Kent [26] has proposed a PBQC scheme that is claimed to be secure, provided that P and reference stations agree with a sequence of bits that cannot be obtained by cheaters. Besides, Malaney has also considered a protocol that entangled pairs are beforehand shared among P and reference stations [20].…”

“…DNB imagery from two successive passes of Suomi NPP on 18 November 2013 are shown in Figure 1a [14]. While these data do not match the exact times of the satellite overpasses, they provide approximate locations of ships and offer a notional ground truth for ship identification.…”

“…The inclusion of meteorological observations from the WOD has also been helpful in this regard. Furthermore, all delayedmode VOS and VOS Climate (VOSClim) data from contributing maritime nations [22] are critical components for ICOADS. A planned modernization of the delayed-mode VOS system under JCOMM could lead to multiple benefits: increasing the quantity of full meteorological reports from ships [22], providing a secure environment for the handling of time-sensitive information such as ship identifiers, creating more accurate marine reference data and products, and potentially even better observational data as new quality control schemes are initiated [40].…”
