.. _task_timeSeriesAntarcticMelt: timeSeriesAntarcticMelt ======================= An analysis task for plotting time series of mean melt rates per ice shelf or Antarctic region along with observations from `Rignot et al. (2013)`_, `Adusumilli et al. (2020) `_, and `Paolo et al. (2023) `_. Component and Tags:: component: ocean tags: timeSeries, melt, landIceCavities Configuration Options --------------------- The following configuration options are available for this task:: [timeSeriesAntarcticMelt] ## options related to plotting time series of melt below Antarctic ice shelves # list of ice shelves to plot or ['all'] for all 106 ice shelves and regions. # See "regionNames" in the ice shelf masks file in regionMaskSubdirectory for # details. iceShelvesToPlot = ['Antarctica', 'Peninsula', 'West Antarctica', 'East Antarctica', 'Larsen_C', 'Filchner', 'Ronne', 'Filchner-Ronne', 'Brunt_Stancomb', 'Fimbul', 'Amery', 'Totten', 'Eastern_Ross', 'Western_Ross', 'Ross', 'Getz', 'Thwaites', 'Pine_Island', 'Abbot', 'George_VI'] # Number of months over which to compute moving average movingAverageMonths = 1 # An optional first year for the tick marks on the x axis. Leave commented out # to start at the beginning of the time series. # firstYearXTicks = 1 # An optional number of years between tick marks on the x axis. Leave # commented out to determine the distance between ticks automatically. # yearStrideXTicks = 1 Ice Shelf and Region Names -------------------------- The ``iceShelvesToPlot`` can be set to ``['all']`` to plot all 106 ice shelves and regions (not recommended, as this is typically a waste of time). Otherwise, it is a list consisting of any subset of the following ice shelves:: ["Abbot", "Amery", "Atka", "Aviator", "Bach", "Baudouin", "Borchgrevink", "Brahms", "Brunt_Stancomb", "Campbell", "Cheetham", "Conger_Glenzer", "Cook", "Cosgrove", "Crosson", "Dennistoun", "Dibble", "Dotson", "Drygalski", "Edward_VIII", "Ekstrom", "Ferrigno", "Filchner", "Fimbul", "Fitzgerald", "Frost", "GeikieInlet", "George_VI", "Getz", "Gillet", "Hamilton", "Hannan", "HarbordGlacier", "Helen", "Holmes", "HolmesWest", "Hull", "Jelbart", "Land", "Larsen_B", "Larsen_C", "Larsen_D", "Larsen_E", "Larsen_F", "Larsen_G", "Lazarev", "Lillie", "Mariner", "Matusevitch", "Mendelssohn", "Mertz", "Moscow_University", "Moubray", "Mulebreen", "Myers", "Nansen", "Nickerson", "Ninnis", "Nivl", "Noll", "Nordenskjold", "Pine_Island", "PourquoiPas", "Prince_Harald", "Publications", "Quar", "Rayner_Thyer", "Rennick", "Richter", "Riiser-Larsen", "Ronne", "Western_Ross", "Eastern_Ross", "Shackleton", "Shirase", "Slava", "SmithInlet", "Stange", "Sulzberger", "Suvorov", "Swinburne", "Thwaites", "Tinker", "Totten", "Tracy_Tremenchus", "Tucker", "Underwood", "Utsikkar", "Venable", "Verdi", "Vigrid", "Vincennes", "Voyeykov", "West", "Wilkins", "Wilma_Robert_Downer", "Withrow", "Wordie", "Wylde", "Zubchatyy"] or these regions made up of 2 or more ice shelves:: ["Antarctica", "Peninsula", "West Antarctica", "East Antarctica", "Ross", "Filchner-Ronne", "IMBIE1", "IMBIE2", "IMBIE3", "IMBIE4", "IMBIE5", "IMBIE6", "IMBIE7", "IMBIE8", "IMBIE9", "IMBIE10", "IMBIE11", "IMBIE12", "IMBIE13", "IMBIE14", "IMBIE15", "IMBIE16", "IMBIE17", "IMBIE18", "IMBIE19", "IMBIE20", "IMBIE21", "IMBIE22", "IMBIE23", "IMBIE24", "IMBIE25", "IMBIE26", "IMBIE27"] The default list of ice shelves and regions was determined to highlight the largest ice shelves and regions along with a representative sample of smaller shelves from different regions. Most of these regions are determined based on the centroid locations given in the supplementary material of `Rignot et al. (2013)`_. Ice shelf regions have been extended into grounded ice and onto the Antarctic continental shelf based which floating ice shelf is closest. The `IMBIE Basins`_ are defined following `Zwally et al. (2012)`_ .. note:: Time series are computed and stored in a NetCDF file for all 106 ice shelves and regions even if only a subset are plotted, allowing you to plot additional ice shelves externally or by re-running MPAS-Analysis. These can be found in ``timeseries/iceShelfAggregatedFluxes.nc`` within your output base directory Other Options ------------- * :ref:`config_moving_average` * :ref:`config_time_axis_ticks` Observations ------------ * :ref:`rignot_melt` * :ref:`adusumilli_melt` Example Result -------------- .. image:: examples/melt_flux_east_ant.png :width: 500 px :align: center .. _`Rignot et al.
