Not able to download S1 GRD on specific coordinates using sentinel hub

Hi,

I will need more detail on the parameters that you are using in your Sentinel-1 GRD request. What is the time range you are using and whether it is an ascending or descending orbit. The spatial/temporal resolution of the data collection is affected by the failure of Sentinel-1B and this might be the reason why you are able to obtain imagery in one AOI but the other AOI.

%%time
for i in range(len(slots)):
evalscript = “”"
//VERSION=3
function setup() {
return {
input: [“VV”,“VH”],
output: { id:“default”, bands: 2,sampleType: SampleType.FLOAT32}
}
}

function evaluatePixel(samples) {
  return [samples.VV,samples.VH]
}

Looking at the Observation Scenarios provided by ESA, I think this is most likely the reason why you don’t get data for these dates.
