Field status flags indicate whether the field is finalised ("f") or preliminary ("p"). - Finalised fields are fixed and will not be updated under the current version number. - Preliminary fields may be updated in future monthly updates if additional data becomes available. Data Array (72x36) Item (1,1) stores the value for the 5-deg-area centred at 177.5W and 87.5N Item (72,36) stores the value for the 5-deg-area centred at 177.5E and 87.5S ----- ------ ----- ------ ------- --------------------- ------------ -------------- | | | | | | | | | | YR | MON | DAY | ROWS | COLS | MISSING_DATA_VALUE | VERSION | FIELD_STATUS | |_____|______|_____|______|_______|_____________________|____________|______________|________ 90N |(1,1) | | | | | | | | | |(1,18) | Equ | | |(1,19) | | | | | | | | | 90S |(1,36)________________________________________________________________________________(72,36)| 180W 0 180E
