[Bug/Feature] Frame search for new ARIA_S1_GUNW collection

[cmarshak]

This is an extension of #198.

Want to be able to search using temporal_baseline_days and frame in this ARIA collection. If I use a >=7.0.9, I am able to get the new collections of ARIA-S1-GUNWs:

import asf_search as asf

opts = asf.ASFSearchOptions(
    shortName='ARIA_S1_GUNW',
    maxResults=10,
)
scenes = asf.search(opts=opts)

Here is metadata for a sample product:

{'centerLat': None,
 'centerLon': None,

  'S1A_IW_SLC__1SDV_20240304T233559_20240304T233626_052838_06650A_CD37'],

 'beamModeType': 'IW',
 's3Urls': [],
 'additionalUrls': []}

So, I know the above product exists. However, when I update the search to include:

import asf_search as asf

opts = asf.ASFSearchOptions(
    shortName='ARIA_S1_GUNW',
    maxResults=10,
    frame=14211
)
scenes = asf.search(opts=opts)

I get no results.

However, I am able to successfully query using temporal baseline:

opts = asf.ASFSearchOptions(
    shortName='ARIA_S1_GUNW',
    maxResults=10,
    #frame=14211,
    temporalBaselineDays=48
)
scenes = asf.search(opts=opts)

Hi! Sorry for the late follow up, this is possible with the asfFrame parameter, which queries FRAME_NUMBER directly.

import asf_search as asf

opts = asf.ASFSearchOptions(
    shortName='ARIA_S1_GUNW',
    maxResults=10,
    asfFrame=14211
)
scenes = asf.search(opts=opts)

At the time of writing this should return 10 scenes from the ARIA_S1_GUNW collection.

Explanation:

asf-search and SearchAPI by default map the frame keyword to CENTER_ESA_FRAME, except when searching with platform, dataset, collections that fit under 'SENTINEL-1A', 'SENTINEL-1B', 'ALOS', in which case they implicitly use FRAME_NUMBER instead. asf-search doesn't do this conversion with the shortName keyword at the moment, so CENTER_ESA_FRAME gets passed along instead. Luckily, asfFrame can cover this basis!

Thank you.

I didn't quite understand your explanation regarding the translation of CMR metadata in asf_search. But fortunately, that's why I use this library and don't have to sweat too much. Thanks for explaining.

This indeed solves the issue!
