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.

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.

November 2017 Reprocessing Information

In Nov 2017 a reprocessing of the MOBY data from M203-M248 was done. This was done to 1) provide a uniform stray light correction (SLC) to the entire data set. M249 onward already was processed with this SLC, so was not changed; 2) Deployments M206, M208 and M210 had spectral data for wavelengths less than 380 nm removed because these deployments used a different type of fiber which caused problems for the SLC at wavelengths below 380 nm.

● 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)
