VIIRS-NPP Time Series

Satellite band averaged data: water-leaving radiance, surface irradiance and solar normalized water-leaving radiance. These values are given as the mean flux (not the total flux) for each band. The total and in-band averages are calculated for each satellite. The in-band is calculated by limiting the relative spectral response to within 1% of the maximum value. A separate data listing (denoted by it's hour) is presented when MOBY collects more than one file per day. Six water-leaving radiances can be calculated from different combinations of MOBY four radiance collectors. The best water-leaving radiance is Lw1, determined from the upper two arms. Lw7 is also included and is calculated from the middle and bottom arms.

VIIRS-NPP RSR files were from the http://www.star.nesdis.noaa.gov/jpss/, the file downloaded was NG_RSRs.zip. Columns 1 and 2 in the VIIRS_F1_Fused_v3_RSR_M*.dat files were used to create the RSRs used to weight MOBY data. The readme file in this directory says "This data is provided by Northrop Grumman under the NPOESS contract (F04701-02-0502, NPOESS A&O)" CONTACT INFO: Mau-Song Chou: mau-song.chou@ngc.com, 27-Sep-11. The file was downloaded from the ftp site on 23-Nov-2011 by Stephanie Flora.



October 2016 Reprocessing Information

In Oct 2016, a reprocessing of the MOBY data began. Three problems are being addressed: 1) the method to extrapolate Kl to the surface has been improved to include Raman scattering and chlorophyll fluorescence; 2) the arm depths used in retrievals was increased by 0.234 m; and 3) a single pixel shift in the data for the RSG collected at a bin factor of 384 for deployments MOBY203 to MOBY253. Initially only MOBY254 to current deployments were reprocessed. These deployments did not have the RSG single pixel shift problem. So for MOBY254 to current deployments only correction 1 and 2 are applied. As the older deployments are processed the data will be added to this directory. MOBY203 to MOBY253 will have had all three corrections applied.



● Lw1 is the Water-Leaving Radiance calculated from LuTop and Kl1(LuTop-LuMid)
● Lw2 is the Water-Leaving Radiance calculated from LuTop and Kl2(LuTop-LuBot)
● Lw7 is the Water-Leaving Radiance calculated from LuMid and Kl3(LuMid-LuBot)

● Lw21 is the Water-Leaving Radiance calculated from LuTop and a modeled Kl
● Lw22 is the Water-Leaving Radiance calculated from LuTop and a modeled Kl
● Lw27 is the Water-Leaving Radiance calculated from LuMid and a modeled Kl
