| The ESA SMOS (Soil Moisture and Ocean Salinity) Mission is planned to be launched in
July 2009. The satellite will measure soil moisture over the continents and surface salinity of
the oceans at resolutions that are sufficient for climatological-type studies. This paper
describes the procedure to be used at the Spanish SMOS Level 3 and 4 Data Processing
Centre (CP34) to generate Soil Moisture and other Land Surface Product maps from SMOS
Level 2 data. This procedure can be used to map Soil Moisture, Vegetation Water Content
and Soil Dielectric Constant data into different pre-defined spatial grids with fixed
temporal frequency. The L3 standard Land Surface Products to be generated at CP34
are:
Soil Moisture products:
maximum spatial resolution with no spatial averaging, temporal averaging
of 3 days, daily generation
maximum spatial resolution with no spatial averaging, temporal averaging
of 10 days, generation frequency of once every 10 days. b’: maximum
spatial resolution with no spatial averaging, temporal averaging of monthly
decades (1st to 10th of the month, 11th to 20th of the month, 21st to last
day of the month), generation frequency of once every decade
monthly average, temporal averaging from L3 decade averages, monthly
generation
Seasonal average, temporal averaging from L3 monthly averages,
seasonally generation
yearly average, temporal averaging from L3 monthly averages, yearly
generation
Vegetation Water Content products:
maximum spatial resolution with no spatial averaging, temporal averaging
of 10 days, generation frequency of once every 10 days. a’: maximum
spatial resolution with no spatial averaging, temporal averaging of monthly
decades (1st to 10th of the month, 11th to 20th of the month, 21st to last
day of the month) using simple averaging method over the L2 products in
ISEA grid, generation frequency of once every decade
monthly average, temporal averaging from L3 decade averages, monthly
generation
seasonal average, temporal averaging from L3 monthly averages,
seasonally generation
yearly average, temporal averaging from L3 monthly averages, yearly
generation
Dielectric Constant products: (the dielectric constant products are delivered together
with soil moisture products, with the same averaging periods and generation
frequency):
maximum spatial resolution with no spatial averaging, temporal averaging
of 3 days, daily generation
maximum spatial resolution with no spatial averaging, temporal averaging
of 10 days, generation frequency of once every 10 days. b’: maximum
spatial resolution with no spatial averaging, temporal averaging of monthly
decades (1st to 10th of the month, 11th to 20th of the month, 21st to last
day of the month), generation frequency of once every decade
monthly average, temporal averaging from L3 decade averages, monthly
generation
seasonal average, temporal averaging from L3 monthly averages,
seasonally generation
yearly average, temporal averaging from L3 monthly averages, yearly
generation. |
