Multi-Satellite Lambertian Equivalent Reflectivity (Noon Normalized) 1 day L3 Global 5.0deg Lat Zones V1 (MSLERNNL3zm)

The Multi-Satellite Lambertian Equivalent Reflectivity (Noon Normalized) 1 day L3 Global 5.0deg Lat Zones data product (MSLERNNL3zm) is derived from observations made by the Nimbus-7 SBUV, and NOAA 9, 11, 14, 16, 17, 18, 19 SBUV/2 instruments (340 nm), Nimbus-7 and Earth Probe TOMS (331 nm), OMI (340 nm) and SeaWiFS (412 nm) from 1978 to 2011. The Noon Normalized (NN) data have been corrected to local noon equator crossing time.

The NN correction was applied only to data between latitudes 60 degrees north and 60 degrees south due to insufficient diurnal data at higher latitudes. The table below lists the date ranges for each instrument (note A = ascending node, D = descending node): Instrument Start Date End Date ------------------ ---------- ---------- Nimbus-7 SBUV 1978-11-01 1990-06-21 NOAA-9 SBUV/2 (A) 1985-02-02 1991-09-03 NOAA-9 SBUV/2 (D) 1990-04-25 1997-05-31 NOAA-11 SBUV/2 (A) 1988-12-01 1995-03-31 NOAA-11 SBUV/2 (D) 1997-07-15 2001-03-26 NOAA-14 SBUV/2 (A) 1995-02-05 2002-09-11 NOAA-14 SBUV/2 (D) 2002-04-09 2006-09-28 NOAA-16 SBUV/2 (A) 2000-10-03 2009-09-15 NOAA-16 SBUV/2 (D) 2008-04-28 2012-12-31 NOAA-17 SBUV/2 2002-07-10 2012-12-31 NOAA-18 SBUV/2 2005-06-05 2012-12-12 Nimbus-7 TOMS 1978-11-01 1993-05-06 EarthProbe TOMS 1996-07-25 2004-06-21 Aura OMI 2005-01-01 2008-12-31 SeaStar SeaWiFS 1998-01-01 2008-12-30 The scene reflectivities of the Earth at blue and ultraviolet (UV) wavelengths (320 nm to 415 nm) are low over most surfaces (except ice and snow), and are almost independent of the seasonal changes in vegetation on land and in the oceans.
