Available products from CPDC

Land products

Level 3 Land products currently available are :

  • L3 Soil Moisture - Global maps
    • 1 day global map of Soil Moisture Values (P11p)
      This product is the daily product, and contains filtered data. The best estimation of soil moisture is selected for each node when several multi-orbit retrievals are available for a given day. A detection of particular events is also performed in order to flag the data.Ascending and descending orbits are still processed separately.The aggregated products are generated from this fundamental product.
    • Global L3 Soil Moisture products, 3 days global map
      The 3-day global product of soil moisture is an aggregation of daily global maps of soil moisture and its associated parameters over a 3 day moving window. The whole Earth's surface is covered in this 3-day product. The distinction between ascending and descending orbits is kept (no ascending/descending orbits aggregation).
    • Global L3 SM products, 10 days global map
      The 10-day global product is a decade aggregation of daily global maps. It contains minimum, maximum and median values of soil moisture and its associated parameters over the decade.The distinction between ascending and descending orbits is kept (no ascending/descending orbits aggregation).
    • Global L3 SM products, monthly global map
      The monthly global product is a monthly aggregation of daily global maps. It provides the mean soil moisture, vegetation optical thickness, RFI statistics over a month, without taking into account the detected events in the daily product. It can be useful for climate monitoring.The distinction between ascending and descending orbits is kept (no ascending/descending orbits aggregation).
  • Dielectric constant maps, 3 days global map
    The 3-day global product of dielectric constant is an aggregation of daily global maps of dielectric constant and its associated parameters over a 3 day moving window. The whole Earth's surface is covered in this 3-day product. The distinction between ascending and descending orbits is kept (no ascending/descending orbits aggregation).

 

Ocean products

Level 3 Ocean products currently available are :

  • Intermediate product OS L2P - Valid Ocean Salinity values
    Intermediate product OS L2P, giving the list of valid L2 data in the Daily OS product and their confidence classes.
  • L3 OS product - Average Salinity values
    Average 10 days & monthly salinity field based on L2P products, at 4 spatial resolutions (25km, 50km, 100km and 200km) 
  • Intermediate product OS L2Q - Valid Debiased Ocean Salinity values
    This product has the same format as the L2P product, with SSS corrected from coastal bias and latitudinal bias. An additional field qualifies the corrected SSS with the information from AUX_MINMAX.
  • L3 OS product - Average Debiased Salinity values
    Average debiased (coastal & latitudinal biases) 10 days & monthly salinity field based on L2Q products, at 4 spatial resolutions (25km, 50km, 100km and 200km)

Common products

  • Daily global polarised brightness temperature product (arranged by incidence angle values) only in full polarization
    This product is a daily product. It includes all brightness temperatures acquired that day, at top of atmosphere level, transformed to ground polarisation reference frame, binned and averaged into fixed angle classes. Ascending and descending orbits are processed separately, and only in full polarisation.
  • RFI probability product, only in full polarization
    Monthly Multi-angular RFI probability : this is the radio frequency interference (RFI) probability for each angle bin computed daily and based on a monthly moving window average. This filtering uses the L3 TB.
