TL;DR: In this paper, the authors compared the estimates of large-scale heat fluxes derived from merchant vessel data within a 4" quadrangle centered on the position of Ocean Weather Station V in the western Pacific Ocean are compared with the estimates from the assumed higher quality weather reports at OWS-V during 1956-70.
Abstract: In this report the estimates of large-scale heat fluxes derived from merchant vessel data within a 4" quadrangle centered on the position of Ocean Weather Station V in the western Pacific Ocean are compared with the estimates from the assumed higher quality weather reports at OWS-V during 1956-70. Comparison of the anomalies of the 6-monthly mean latent heat flux estimates from the longterm means of the two data set\ revealed significantly different patterns in the latent heat flux, particularly dunng the 1956-66 period. Investigation of the monthly mean properties used to compute the heat flux estimates showed a statistically significant trend in the differences between the sea surface temperatures. The trend in the SST differences is believed to result from the inclusion of low-precision merchant vessel data collected prior to 1962. There is also a suggestion that this trend may have resulted from sampling bias (in terms of data density and bias in location of the observations). The results indicate that the use of time- and space-averaged properties or heat flux estimates derived from the TDF-I I file requires careful screening of the reports to provide unbiased estimates of air-sea energy transfer processes.

TL;DR: The present state of marine weather data technology may be broken into two major categories: 1) "in-situ" environmental measurements; and 2) remote sensing of the marine environment as discussed by the authors.
Abstract: The present state of marine weather data technology may be broken down into two major categories: 1) "in-situ" environmental measurements; and 2) remote sensing of the marine environment. In-situ weather measurements are routinely taken by observers on cooperating commercial vessels and aircraft crossing the oceans, as well as on the few remaining ocean weather station vessels. To an increasing extent however, observations of surface weather are being taken by automated buoys of several types. Coastal winds and waves are being observed by automated recording devices along the U.S. coastline. Remote sensing from operational satellites has also become an important source of data. Meteorological and surface oceanographic data is now available in real-time on a routine basis from several satellite systems, and development is continuing on new and improved types of sensors. Land-based remote sensors, particularly involving microwave applications, also show great promise for the near future.
