Missing NDVI #2

Open skmorgane opened 9 years ago

skmorgane commented 9 years ago

There are a variety of gaps in the LANDSAT time series. I think we should look into filling these using MODIS and AVHRR to create a continuous monthly NDVI record for the site. Step 1: see how our existing MODIS data for Portal correlates with the overlapping LANDSAT data.

Have now bootstrapped a short-term solution for this by filling in gaps at the month-level with corrected MODIS data, but this is occurring in a separate file (MODIS_LANDSAT.R) using the output from "LS_time.R"). Instead, Modis should be treated as just another satellite and combined in this file. That way it is included in all months, instead of just filling gaps.
