Hi asniyori,

Are you using in-situ data from the NSIDC? If so, please let me know which data set and I can provide guidance on the conversion. You can explore the SMAP validation data sets here: https://nsidc.org/data/smap/validation-data

Re: NSIDC-0079 (Sea Ice) download: having to restart download frequently

This is a known issue with the Python script generated by the Data Access Tool. Our team is working on a solution, but in the meantime, I would recommend another data access method (like NASA Earthdata Search https://search.earthdata.nasa.gov/search?q=NSIDC-0079%20V004) I apologize for the inconveni...

Question: How to place hdf raster in correct location

Re: How to place hdf raster in correct location

Hi etis, It looks like the reason that the .h5 is failing to read in the correct location is that the CRS information is not included in the metadata in a way that QGIS can read it/interpret it. From what I have read, reprojecting an .h5 file in QGIS is tricky. I would recommend using Earthdata sear...

Re: SMAP Level-4 soil moisture data

There are a few reasons that the soil moisture data values in SMAP Level-4 data products may vary from what you expect in a particular region. The first step a data user should take in investigating apparently anomalous values is to look at the rich quality information and other data flags contained...

Re: How to place hdf raster in correct location

Hi etis, What method did you use for importing the data into QGIS? Also, could you include a screenshot to demonstrate the location issue? I suspect that the reason for this issue is because the data are in a 1D array and not a 2D array. It might be worth re-downloading the data reformatted as GeoTI...
