The LEVEL 1 data includes additional variables, and has undergone some quality control processing to
eliminate reports with erroneous positions. The header for these files is:
BuoyID,Year,Month,Day,Hour,Min,Sec,Lat,Lon,GPSdelay,BPT,BP,Ts,Ta,Th,Batt
where:
- Year, Month, Day, Hour, Min, Sec => Time for the variables BPT,BP,Ts,Ta,Th,Batt
- GPSdelay ==> Difference in minutes between the time of the position measurement and other variables.
- BPT ==> Barometric Pressure Tendency<
- BP ==> Barometric Pressure<
- Ts ==> Surface Temperature C
- Ta ==> Air Temperature C (typically at 1m)
- Th ==> Hull Temperature C (inside the buoy)
- Batt ==> Battery Voltage
The variables BPT, BP, Ts, Ta, and Th were not quality controlled, except to ensure all values were within reasonable ranges.
Values outside of these ranges were set to -999:
BPT: -40 to 40 hPa/hr
BP: 900 to 1100 hPa
Ts: -60 to 40 C
Ta: -60 to 40 C
Th: -60 to 40 C
The data is in CSV format and currently can be downloaded in bulk by year, or by individual buoy.
Additional options to allow searches for data or for individual buoys by region, logistics, buoy type, available variables, and time constraints coming soon.
