Maritime Guide

Column 1: ERACLIM Inventory ID
Column 2: Original Data Owner - The original archive that was assimilated into the ERACLIM inventory or the individual's name if provided by a single party.
Column 3: Provided Station ID - Typically this would be expected to be the ship/cruise name.
Column 4-5: Start & End - Start and end day of the record with format YYYY-MM-DD, enter the very first and last day, do not worry about gaps.
Column 6: Time Resolution - Number of Observations per day. For example, "24, 5, 3", would indicate hourly observations and 5 and 3 times-daily observations. If the number varies, enter the highest frequency value.
Column 7: Estimated Station Days - Approximate number of days with data for this record.
Column 8-19: Climate Variables - Indicates with a 1/0 (1 = True, 0 = False) whether the record contains information for a particular climate variable.

• ws - wind speed
• dir - wind direction
• ps - air pressure
• pst - temperature of the thermometer next to the barometer
• sat - surface air temperature (includes max/min)
• sst - sea surface temperature
• rH - relative humidity
• sH - specific humidity
• aH - absolute humidity
• dew - dewpoint temperature
• wet - wetbulb temperature
• cloud - cloud cover

Column 20-25: Level - The stage of rescue/digitisation. Formatting is six digits, 1 or 0 for true/false.

• Stage 0 - Physical copy of the data found, no imaging or digitisation done.
• Stage 1 - Data have been imaged.
• Stage 2 - Data have been digitised
• Stage 3 - Data have undergone initial/basic quality control to check that values make physical sense.
• Stage 4 - Rigourous quality control done, e.g. do newly digitised daily data = existing published monthly values?
• Stage 5 - Data has been subjected to homogeneity tests and has been adjusted if neccessary.

Column 26: Link to file - Online access to data if available.
Column 27: Comment - any important comments go here, gaps, known pressure adjustments, suspected inhomogeneities etc...
