The following frequently asked questions (FAQ) and answers are relevant to the NDBC TAO Array deployments. For additional information about the NDBC stations, the NDBC FAQ page may be helpful. |
What
climatologies are used in TAO data display? Reynolds and Smith AOI SST Climatology
(1971 - 2000) Kessler Objective Analysis of XBT and CTD
Temperatures The CTD data used in the analysis consist of all the available data from the earliest years these observations were taken through 1991. The XBT data range in time from 1970 to 1987. For further information about the methods used to create the Kessler climatology, please refer to Kessler, W.S., 1990: "Observations of long Rossby waves in the northern tropical Pacific". J. Geophysical Research, 95(C4), 5183-5217, and Kessler, W.S. and J.P. McCreary, 1993: "The annual wind-driven Rossby wave in the subthermocline equatorial Pacific". J. Physical Oceanography, 23(6), 1192-1207. This climatology is used for gridding the TAO / TRITON subsurface temperatures in Longitude-Depth and Latitude-Depth sections. For more information on how these TAO / TRITON data are gridded, see the zonal-depth gridding and meridional-depth gridding web pages. COADS Winds (1946 - 1989) COADS Relative Humidity (1946 -
1989) This climatology is used for computing TAO / TRITON RH anomalies, and for gridding RH in the Lat-Lon Maps and Latitude-Time and Time-Longtitude section plots. For example plots of RH see the Section Plots on the TAO / TRITON Data Display web page. For information on these gridding methods, see the TAO / TRITON gridding web pages. 20°C Isotherm depth This climatology is used for computing TAO / TRITON 20 degree C Isotherm depth anomalies, and for gridding 20 C depths in the Lat-Lon Maps and Latitude-Time section plots. For example plots of 20C Depth see the TAO / TRITON Data Display web page. For information on these gridding methods, see the TAO / TRITON gridding web pages. Dynamic Height This climatology is used to compute Dynamic Height anomalies, and for gridding Dynamic Heights in the Lat-Lon Maps and Latitude-Time section plots. For example plots of Dynamic Height see the TAO / TRITON Data Display web page. For information on these gridding methods, see the TAO / TRITON gridding web pages. |
What
gridding methods are used in TAO data
display? Some of the gridding methods utilize climatological averages in the gridding process. For plots and background info on these climatologies, see the TAO / TRITON Climatologies page. These gridded fields have been created as "quick look" fields for visual display. Users of these fields are cautioned that they may not be optimally contstructed for detailed scientific analyses. We encourage users of the TAO / TRITON data to do their own gridding for any serious scientific computations. Ungridded data are available by anonymous FTP (Host: tao.noaa.gov, Directory: taodata) and on the TAO / TRITON Data Display page. Buoy gridding |
