title: Expansion computed for the quadratic map for different numbers of individual parameters and intervals of parameters using dynamically refined partitions

description: Expansion data computed for the quadratic map by the program that implements the algorithms introduced in the paper “Rigorous computation of expansion in one-dimensional dynamics” by Paweł Pilarczyk, Michał Palczewski and Stefano Luzzatto.
This computation was conducted for 2^n+1 uniformly spaced parameter values in [1.4,2] or for 2^n intervals of parameters of the same size (up to rounding) into which the interval [1.4,2] was split, for n=10,…,17, using dynamically refined partitions of up to 1000 intervals outside the critical neighborhood of radius δ=0.001.
There are several datasets in this package, obtained for the different values of n. The files run20e10.csv through run20e17.csv were obtained for 2^10 through 2^17 intervals of parameters. The files run20e20.csv through run20e27.csv were obtained for 2^10+1 through 2^17+1 individual values of parameters.
The data is in the CSV format, with the first row containing column labels. The contents of the columns is the following:

level — the level of subdivision of the parameter interval (e.g. 10 for 2^10=1024 subintervals)
num — the identifier of the data piece in the collection at the given subdivision; the identifiers begin with 0
parMin — the left endpoint of the parameter interval (minimal parameter value)
parMax — the right endpoint of the parameter interval (maximal parameter value)
k — the total number of intervals on which the graph representation of the map was built (the critical neighborhood is counted here, too)
delta — the radius δ of the critical neighborhood
lambda — the computed expansion exponent λ
logC — log C if the constant C was computed, otherwise 0
lambda0 — the constant λ₀ if it was computed, otherwise 0
period — the period of a periodic orbit found (0 if none)
lambdaMax — an upper bound on the expansion exponent of the periodic orbit found (0 if none)
distFrom0out — the minimum guaranteed distance of the periodic orbit from 0
distFrom0in — an upper bound on the distance from 0 during the closest approach to 0
compTime — the computation time measured in seconds

title: Expansion computed for the quadratic map for 1025 parameters using dynamically refined partitions with different radii of the critical neighborhood

description: Expansion data computed for the quadratic map by the program that implements the algorithms introduced in the paper “Rigorous computation of expansion in one-dimensional dynamics” by Paweł Pilarczyk, Michał Palczewski and Stefano Luzzatto.
This computation was conducted for 1025 uniformly spaced parameter values in [1.4,2] using dynamically refined partitions of up to k intervals outside the critical neighborhood of radius δ. There are four datasets in the package obtained for a few different values of k and δ:– run20e00.csv: δ=0.001, k=3000– run20e01.csv: δ=0.1, k=1000– run20e02.csv: δ=0.01, k=1000– run20e03.csv: δ=0.001, k=1000

title: Holocene Northern Hemisphere annual SAT and SST fields reconstructed using paleoclimate data assimilation

description: This URL contains two files. The one is a compressed .rar file, which includes the code and basic data required to conduct the paleoclimate data assimilation (PDA) experiment for reconstructing Holocene Northern Hemisphere (NH) annual temperatures. The other file is a .nc file that contains the reconstructed, spatially-completed Holocene NH annual surface air temperature (SAT) and sea surface temperature (SST) fields (Abbreviation: HNHTR). These fields have a spatial resolution of 3.75° and a temporal resolution of 100 years, reconstructed using the PDA method by fusing 2,442 annual SAT records and 166 annual SST records with transient model simulations covering the entire Holocene (i.e., 12-0 ka BP). The PDA experiment involved 50 Monte Carlo realizations, each has a distinct prior ensemble and assimilates randomly selected 75% of the 2,608 SAT and SST records. As a result, the .nc file contains 50 SAT and SST fields.
