I just put this in terminal and its returning this:

$ curl "https://cmr.earthdata.nasa.gov/search/collections?doi\10.5067/CALIOP/CALIPSO/LID_L2_05kmCLay-Standard-V4-10=doi"

<?xml version="1.0" encoding="UTF-8"?><errors><error>Parameter [caliop/_calipso/_lid_l_2_05km_c_lay_standard_v_4_10] was not recognized.</error></errors>

 

Can you please help correct the format?

  1. What is an example collection result that shows the DOI? (So we can tell the DOI search actually works)

     

    The request https://cmr.earthdata.nasa.gov/search/collections?doi=10.5067/CALIOP/CALIPSO/LID_L2_05kmCLay-Standard-V4-10 (removed the weird "=doi" at the end) produces result:

    <results>
      <hits>0</hits>
      <took>92</took>
      <references/>
    </results>

    A wildcard request https://cmr.earthdata.nasa.gov/search/collections?doi=10.5067*&options[doi][pattern]=true&page_size=1 produces:

    <results>
      <hits>715</hits>
      <took>9</took>
      <references>
        <reference>
          <name>
            AIRS-AMSU variables-CloudSat cloud mask, radar reflectivities, and cloud classification matchups V3.2 (AIRSM_CPR_MAT) at GES DISC

          <revision-id>4</revision-id>
        </reference>
      </references>
    </results>

    The location link shows a web page for it, but the web page omits any DOI, as does https://cmr.earthdata.nasa.gov/search/collections.json?concept_id=C1236224182-GES_DISC the JSON result for just that collection:

These data contain collocated: AIRS/AMSU retrievals at AMSU footprints, CloudSat radar reflectivities, and MODIS cloud mask. These data are created within the frames of the MEaSUREs project.\n\nThe basic task is to bring together retrievals of water vapor and cloud properties from multiple \"A-train\" instruments (AIRS, AMSR-E, MODIS, AMSU, MLS, CloudSat), classify each \"scene\" (instrument look) using the cloud information,\nand develop a merged, multi-sensor climatology of atmospheric water vapor as a\nfunction of altitude, stratified by the cloud classes. This is a large science\nanalysis project that will require the use of SciFlo technologies to discover and organize all of the datasets, move and cache datasets as required, find\nspace/time \"matchups\" between pairs of instruments, and process years of\nsatellite data to produce the climate data records.\n\nThe short name for this collection is AIRSM_CPR_MAT\n\nParameters contained in the data files include the following:\nVariable Name|Description|Units \n CH4_total_column|Retrieved total column CH4| (molecules/cm2)\n CloudFraction|CloudSat/CALIPSO Cloud Fraction| (None)\n CloudLayers| Number of hydrometeor layers| (count)\n clrolr|Clear-sky Outgoing Longwave Radiation|(Watts/m**2)\n CO_total_column|Retrieved total column CO| (molecules/cm2)\n CPR_Cloud_mask| CPR Cloud Mask |(None)\n Data_quality| Data Quality |(None)\n H2OMMRSat|Water vapor saturation mass mixing ratio|(gm/kg)\n H2OMMRStd|Water Vapor Mass Mixing Ratio |(gm/kg dry air)\n MODIS_Cloud_Fraction| MODIS 250m Cloud Fraction| (None)\n MODIS_scene_var |MODIS scene variability| (None)\n nSurfStd|1-based index of the first valid level|(None)\n O3VMRStd|Ozone Volume Mixing Ratio|(vmr)\n olr|All-sky Outgoing Longwave Radiation|(Watts/m**2)\n Radar_Reflectivity| Radar Reflectivity Factor| (dBZe)\n Sigma-Zero| Sigma-Zero| (dB*100)\n TAirMWOnlyStd|Atmospheric Temperature retrieved using only MW|(K)\n TCldTopStd|Cloud top temperature|(K)\n totH2OStd|Total precipitable water vapor| (kg/m**2)\n totO3Std|Total ozone burden| (Dobson)\n TSurfAir|Atmospheric Temperature at Surface|(K)\n TSurfStd|Surface skin temperature|(K)\nEnd of parameter information",

  2. If you pull the collection down in UMM JSON, you can see the DOI as a top level element on the collection.
