MODIS-Aqua-land 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.

Around the 9th of February 2010 Stephanie noticed the LuMid and Bot radiances were getting very close to each other. This continued until around 25 Feb when it became very difficult to get any good data. After the 5th of April all data were marked bad. After Mike performed post cals he found LuMid response had increased by 15%. This confirmed that LuMid died during the deployment. So all LuMid data is marked bad from 9 Feb to the end of the deployment. Lw2 data calculated from LuTop and Kl (top,bot) are made available for this deployment.

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
