Google Earth Engine: Find the day of year in a time series data where a certain value is found

Question

I have a time series of Sentinel-1 data (s1) for my AOI. Each image also has a DOY BAND (Day-of-year) which I had added.

I have another image (image2) for the same AOI, it has only one band with backscatter values.

I need to find the DOY (for each pixel) from the time-series s1 (which is an image collection) where time_series pixel value >= image2 pixel value, for each pixel position.
