Radar Altimeter Product

The level HY-2 Satellite Radar Altimeter Data can generate level 1 level 2 and level 3 data product through preprocess, inversion and statistical average.

Level 1 Product:
      1A: The data after time identifying and position.       1B: The data after pass, FFT format transfer, height tracking value and slopes transfer, and with position information and description information.

Level 2 Product:
      The product data is generated after the level 1 data inversion and with ocean and land identification and quality controlling.
      The level 2 product data can be divided to: Interim Geophysical Data Records (IGDR), Sensor Geophysical Data Records (SGDR) and Geophysical Data Records (GDR).
      Interim Geophysical Data Records is generated from the MOE orbit determination data by the method of waveform and etc. It is the record without calibration. It is finished within two hours after obtaining the MOE data.
      Sensor Geophysical Data Records is similar with the IGDR and GDR, but the SGDR includes waveform data. The SGDR product is finished within two hours after obtaining the MOE data.
      Geophysical Data Records is generated from POE orbit determination data by the method of waveform and etc. It is finished within 30 days after obtaining the satellite data.

Level 3 Product:
      It is the monthly average and annual average meshing product. It includes significant wave height, the sea surface wind speed and sea surface height abnormality mesh, monthly average and annual average product.
