Update: I've made some progress on determining the source of this issue. It seems related to the source dataset's variables. When I use 2 opendap urls with 4 parameterized variables things work fine

Using 2 urls like:

https://podaac-opendap.jpl.nasa.gov:443/opendap/allData/ghrsst/data/GDS2/L4/GLOB/JPL/MUR/v4.1/2002/152/20020601090000-JPL-L4_GHRSST-SSTfnd-MUR-GLOB-v02.0-fv04.1.nc?time[0:1:0],lat[0:1:17998],lon[0:1:35999],analysed_sst[0:1:0][0:1:17998][0:1:35999],analysis_error[0:1:0][0:1:17998][0:1:35999],mask[0:1:0][0:1:17998][0:1:35999],sea_ice_fraction[0:1:0][0:1:17998][0:1:35999]

I get back a dataset :

<xarray.Dataset> Dimensions: (lat: 17999, lon: 36000, time: 2) Coordinates: * lat (lat) float32 -89.99 -89.98 -89.97 ... 89.97 89.98 89.99 * lon (lon) float32 -179.99 -179.98 -179.97 ... 179.99 180.0 * time (time) datetime64[ns] 2018-04-22T09:00:00 2018-04-23T09:00:00 Data variables: analysed_sst (time, lat, lon) float32 dask.array<shape=(2, 17999, 36000), chunksize=(1, 1000, 1000)> analysis_error (time, lat, lon) float32 dask.array<shape=(2, 17999, 36000), chunksize=(1, 1000, 1000)> Attributes: Conventions: CF-1.5 title: Daily MUR SST, Final product

however if I omit the parameterized data variables using urls such as:

https://podaac-opendap.jpl.nasa.gov:443/opendap/allData/ghrsst/data/GDS2/L4/GLOB/JPL/MUR/v4.1/090000-JPL-L4_GHRSST-SSTfnd-MUR-GLOB-v02.0-fv04.1.nc

I get back an additional variable:

<xarray.Dataset> Dimensions: (lat: 17999, lon: 36000, time: 2) Coordinates: * lat (lat) float32 -89.99 -89.98 -89.97 ... 89.97 89.98 89.99 * lon (lon) float32 -179.99 -179.98 -179.97 ... 179.99 180.0 * time (time) datetime64[ns] 2018-04-22T09:00:00 2018-04-23T09:00:00 Data variables: analysed_sst (time, lat, lon) float32 dask.array<shape=(2, 17999, 36000), chunksize=(1, 1000, 1000)> analysis_error (time, lat, lon) float32 dask.array<shape=(2, 17999, 36000), chunksize=(1, 1000, 1000)> mask (time, lat, lon) float32 dask.array<shape=(2, 17999, 36000), chunksize=(1, 1000, 1000)> sea_ice_fraction (time, lat, lon) float32 dask.array<shape=(2, 17999, 36000), chunksize=(1, 1000, 1000)> dt_1km_data (time, lat, lon) timedelta64[ns] dask.array<shape=(2, 17999, 36000), chunksize=(1, 1000, 1000)> Attributes: Conventions: CF-1.5 title: Daily MUR SST, Final product

In the first case (with the parameterized variables) I achieve the expected result (data is stored on S3). In the second case (no parameterized variables), store store is never included in the graph the workers seem to stall.
