NOAA 1/4 degree daily Optimum Interpolation Sea Surface Temperature (OISST) menyediakan bidang suhu laut lengkap yang dibuat dengan menggabungkan pengamatan yang disesuaikan biasnya dari berbagai platform (satelit, kapal, pelampung) pada petak global reguler, dengan kesenjangan yang diisi dengan interpolasi.
Data satelit dari Advanced Very High Resolution Radiometer (AVHRR) memberikan input utama yang memungkinkan cakupan temporal-spasial yang tinggi mulai dari akhir tahun 1981 hingga saat ini.
Set data OISST memiliki data satu hari yang diproses dua kali. Pertama, versi awal hampir real-time dirilis dengan jeda 1 hari, dan versi akhir dengan jeda 14 hari. Versi akhir menggunakan hari tambahan untuk
penghalusan, dan koreksi bias zonal selain menggantikan
versi awal.
