[5.x]: Fix GRIB IOSP so time coords are monotonically increasing, for 1-D time datasets only

1

## Description of Changes Fix GRIB IOSP code that creates time coordinate variables from a set of irregularly overlapping time intervals to ensure the resulting time coordinate is monotonically increasing....

[5.5.3]: Fix GRIB IOSP to ensure time coordinates are monotonically increasing

### Versions impacted by the bug v5.x ### What went wrong? For variables where the data values are valid on a time interval, e.g., total precipitation, the GRIB IOSP calculates...

### Versions impacted by the bug v5.x ### What went wrong? Opening this THREDDS catalog from the NASA GES DISC resulted in repeated authentication popup windows: https://gpm1.gesdisc.eosdis.nasa.gov/thredds/catalog/aggregation/GPM_3IMERGHHL.06/2021/catalog.xml I did not...

Handling of CDL `long`, `int`, and `uint64`

4

In CDL, `long` is a [synonym](https://www.unidata.ucar.edu/software/netcdf/documentation/NUG/_c_d_l.html#cdl_data_types) for the `int` data type (4-byte signed integer). In netCDF-Java, [`ArrayType.LONG`](https://github.com/Unidata/netcdf-java/blob/01d8aef292cc7bbcee556657129bc88694613d65/cdm/core/src/main/java/ucar/array/ArrayType.java#L25) and [`ArrayType.ULONG`](https://github.com/Unidata/netcdf-java/blob/01d8aef292cc7bbcee556657129bc88694613d65/cdm/core/src/main/java/ucar/array/ArrayType.java#L32) are 8-byte integers but they use `long` and `ulong` when writing...

Trying NUG BNF example using ncgen for empty netCDF file, wrong size

2

While working on reorganizing the NUG, I started adding CDF-2 and CDF-5 to the nc-3 (CDF-1) BNF description. I tried out some of the examples using ncgen to generate simple...

Replace all references to 'motherlode.ucar.edu/thredds' with 'thredds.ucar.edu/thredds' in bundles and plug-ins

3

Need to replace references to `http://motherlode.ucar.edu/thredds` with `http://thredds.ucar.edu/thredds` in all current IDV bundles, plug-ins, and documentation. Here's the output from a `grep -R 'motherlode.ucar.edu/thredds' software/idv`: [mlode-idv.txt](https://github.com/Unidata/IDV/files/1149405/mlode-idv.txt) There are 3254 instances...

Given concerns about the future of Java3D, need to investigate other options that might be used as a replacement in IDV and VisAD (see visad/visad#115).
