The Oleander Project

Statistics of XBT data stored in the Global Telecommunication System (GTS)


XBT probes are launched onboard the MV Oleander and data are logged to a computer where they are processed and formatted for transmission in real-time via Standard-C to Siver Spring (Maryland). Data that reach Silver Spring are automatically transferred via file transfer protocol (ftp) to AOML and undergo rigid automatic and visual quality control (QC) procedures. Data that pass QC are stored in the GTS and are then used by national and international organizations, universities and government laboratories for weather and climate forecasting and for climate reasearch.

The bar graphs below are graphical descriptions of the actual number of real-time XBT observations, from 2000 to 2017, that were launched from the MV Oleander and ended up in the GTS server. They are grouped by year, month and longitude.

Actual number of data stored in the GTS grouped by Year

Annual

Total number of XBT data stored in the GTS by year from 2000-Present. Data are from XBTs deployed from the MV Oleander between New Jersey and Bermuda. XBTs, XBT equipment, computers and transmission onboard the MV Oleander are provided by NOAA/AOML.

Actual number of data stored in the GTS grouped by Month

Monthly

Total number of XBT data stored in the GTS by month from 2000-Present. Data are from XBTs deployed from the MV Oleander between New Jersey and Bermuda. XBTs, XBT equipment, computers and transmission onboard the MV Oleander are provided by NOAA/AOML.

Actual number of data stored in the GTS grouped by Degree Longitude

Zonal

Total number of XBT data stored in the GTS by degree longitude from 2000-Present (74°W [74°W to 73.5°W], 73°W [73.49°W to 72.5°W], 72°W [72.49°W to 71.5°W], 71°W [71.49°W to 70.5°W], 70°W [70.49°W to 69.5°W], 69°W [69.49°W to 68.5°W], 68°W [68.49°W to 67.5°W], 67°W [67.49°W to 66.5°W], 66°W [66.49°W to 65.5°W], and 65°W [65.49°W to 64°W]). Data are from XBTs deployed from the MV Oleander between New Jersey and Bermuda. Note the high-density mode between 74°W and 70°W, a region of high scientific interest. XBTs, XBT equipment, computers and transmission onboard the MV Oleander are provided by NOAA/AOML.
