raadtools dev

  • Added a consolidated CITATION for raadtools, blueant, and bowerbird.

  • ocfiles() now sets type to "L3m" by default (was L3b), and varname to "CHL" (was RRS).

  • readtopo() now defaults to GEBCO 2023.

  • Replace old form of time_since_melt with fancy new duckdb process and checked it's working with extract().

  • Fixed matching files bug for 8 day intervals.

  • Fixed readCHL_month() to work with extract.

  • Modified time delta for matching files to "monthly".

  • Now reading GHRSST COGs, so using terra internally to ensure data is scaled correctly. Now dep on raadfiles 0.1.4.9003.

  • Add nuyina data set.

  • This package now does the date/band expansion for SOSE (to help free raadfiles from dependencies), fasticefiles() is no longer exported but there is a new function fraser_fasticefiles() to get the files.

  • readchla() now returns a mean from all input dates, and no longer supports Johnson alg.

  • Fix readcurr.

  • NSIDC netcdf files needed to disable 'rescale'. We don't currently control that.

  • New scheme for NSIDC netcdf files. We now use these directly, there's no use for 'vrt_dsn'. Now depending on raadfiles 0.1.3.9041, in raadfiles the dates are culled to be distinct. Here the empty dates (no variable exists in the shell netcdf), we remove those in icefiles().

  • raadtools now imports package {reproj}, fixes #135.

  • New function read_par() contributed by Kimberlee Baldry @KimBaldry.

  • Removed rgeos and maptools.

  • Removed rgdal imports, replaced with raster and reproj.

*Function readice() has been expanded to allow 'hemisphere = "both"' and for 'xylim' to be a full raster grid (terra or raster format). If 'both' is specified the warper is applied to VRT versions of the NSIDC files, which allows them to be combined in one reprojection step. In this case 'xylim' can be specified, to give a projected grid of any form. If not supplied (when hemisphere = 'both') then longlat raster at 0.25 degrees is assumed.

  • New function read_ccmp() and ccmp_files() for RSS Cross-Calibrated Multi-Platform Ocean Surface Wind Project.

  • Function topofile() now returns VRT-augmented text for some sources where missing metadata needs to be added, not always just a file path.

  • Function readtopo() and readbathy() now accept terra::ext or raster::extent or just numeric objects for 'xylim'. Alternatively these can be a terra SpatRaster or a raster BasicRaster (RasterLayer, RasterBrick, or RasterStack) as a template target raster for crop and resize, or reprojection to new raster grid. The 'resample' argument controls the kind of sampling when regridded or warped. (i.e. if xylim is extent, you get crop(), if it's a grid, you get it remodelled to the grid. extent doesn't need crs, grid does).

  • Now using imports from terra and vapour, primarlily for topofile() and readtopo() for now.

  • readtopo() and topofile() source "ga_srtm" is no longer available (better done with NASADEM_be and gdal warp anyhow). Also "george_v_terre_adelie" and "srtm" no longer available.

  • Fixed documentation for units in surface currents, thanks Ryan Reisinger. #117

  • New function query_grid() to build a query data frame for extract(function, ...) workflows.

  • New function readCHL_month() to read NASA's monthly CHL files.

  • New function table_vgos() to read surface current values as a data frame.

  • readcurr() and other altimetry read functions now behave consistently for use of 'lon180', default is Atlantic view but can be set to FALSE to give Pacific view (and behaves correctly no matter the source file arrangement). The other functions include readssh(), read_sla_daily(), read_ugosa_daily(), read_vgosa_daily(), read_ugos_daily(), read_vgos_daily(), read_err_daily().

  • New data set stations with locations of Mawson, Davis, and Casey.

  • New functions read_amsre_ice(), read_amsr2_ice(), read_amsr2_3k_ice() to round out read of AMRS2 and AMSRE at 6km and 3km resolutions using new file list functions from raadfiles.

  • AMSR read ice functions now correctly apply xylim argument.

  • Lead frequency functions read_leads_clim(), read_leads_north_clim(), read_leads_south_clim().

raadtools 0.6.0

  • Updated 'kerguelen' topo to revised version (2019).

  • Function readfastice() now defaults to the 2020 updated circumpolar files.

  • Now importing fasticefiles() from raadfiles.

  • Align to updated raadfiles (0.1.3.9006) for new OISST file paths.

raadtools 0.5.5

  • readamps_d1wind() now correctly read the right bands. New function readamps_d2wind() to read the d2 grid.

  • Bit of a clean up around AMPS and Copernicus documentation.

  • New function read_cersat_ice() for 12.5 km SSM/I.

  • New function read_geoid() to read geoid.

  • New function read_sose() to read SOSE Southern Ocean State Estimate layers by level and date, no capacity for xylim or multiple dates (only monthly for now). Explore available variables with sose_monthly_varnames() and available files with 'raadfiles::sose_monthly_files()'.

  • Add SMAP functions salfiles() and readsal() for surface salinity.

  • Fixed longstanding bugs in several functions that treated latest = TRUE as an override of the date argument. The latest argument now only applies if date is missing. Thanks to @maierhofert #96.

raadtools 0.5.2

  • Add GEBCO 2019 "gebco_19" topography.

  • readchla() is now parallelized with furrr, and includes a grid specification argument

  • distance_to_ice() and distance_to_ice_edge() now include the date on the output and are strictly not vectorized.

  • new function readfsle.

raadtools 0.5.0

  • Removed dependency on 'sosoc/croc' package, by internalizing the imported functions.

  • Now using new raadfiles approach.

  • New function to return polar coastline with 'polar_map' function.

  • First parts of REMA data now available from readtopo, with "rema_8m", "rema_100m" and read_rema_tiles (the 8m index).

  • AMPS data now supports basic access for 10km "d2" files, with amps_d1files moved to raadfiles.

  • Fixed the grid specification for d1 AMPS (and added d2).

  • New topo option "ga_srtm" for the Australian 1-second DEM (~30m), file available only on nectar for now.

  • New readice_area function for "NSIDC SMMR-SSM/I Nasateam sea ice concentration".

  • Topography readtopo and topofile gain topo = "ramp" option for Radarsat Antarctic digital elevation model V2, elevations relative to the the OSU91a geoid.

  • Topography functions readtopo and topofile now support topo = 'ibcso_is' and topo = 'ibcso_bed' for the ice surface and bedrock versions respectively. The default 'ibcso' remains synonomous with 'ibcso_is'.

  • "cryosat2" and "lake_superior" added to readtopo

  • establish readice_daily and readice_monthly model for future separation

  • re-instated monthly NSIDC north and south hemisphere

  • now use raadfiles for AMPS

  • readchla returns, now providing MODISA/SeaWiFS at native mapped resolution for a given set of input dates (the mean is calculated from the daily L3 bins) for either 'nasa' or 'johnson' algorithm

  • removed prod files

  • read rapid response is not fixable in place, but now uses the raadfiles-like approach

  • read functions now default to latest = TRUE rather than returning the first available time

  • readssh and sshfiles are now only daily, using the Copernicus sources

  • new Copernicus source for altimetry products from ftp.sltac.cls.fr/Core/ provided by new functions read_ugosa_daily,read_adt_daily, read_ugos_daily, read_sla_daily, read_vgos_daily, read_vgosa_daily, read_err_daily

  • speed up for extract(function, xyt)

raadtools 0.4.0

  • a sensible value (4e9) for raster maxmemory is set on startup which means that fewer temp files will be created unnecessarily

  • now imports orsifronts rather than using old bespoke copies

  • startup is now much more robust

  • raadtools now imports raadfiles, for OISST and GHRSST files

  • raadtools::sstfiles() and c. now works without attaching the package

  • ghrsst gains inputfiles, and is now useably fast for track extraction
