Planet is improving its algorithm for calculating Surface Reflectance in PlanetScope and RapidEye products. Planet is also now producing
analytic_sr assets under the existing
REOrthoTile item types.
The new Surface Reflectance algorithm should help reduce scene-to-scene difference due to rapidly varying atmospheric conditions. Reference the updated white paper on the support page: https://support.planet.com/hc/en-us/articles/360012629573-Planet-Surface-Reflectance-Product
analytic_sr assets are available under the existing
REOrthoTile items listed in the Dev Center: https://developers.planet.com/docs/data/items-assets/

All bands now have human readable band descriptions (ie red, blue, green, NIR) and the color interpretation for 4-band imagery now reflects the BGRN band: band ordering in GIS tools such as QGIS or GDAL will now correctly reflect BGRN ordering instead of assuming RGBN.
