Local Climatological Data (LCD) are summaries of climatological conditions from airport and other prominent weather stations managed by NWS, FAA, and DOD. The product includes hourly observations and associated remarks, and a record of hourly precipitation for the entire month. Also included are daily summaries summarizing temperature extremes, degree days, precipitation amounts and winds. The tabulated monthly summaries in the product include maximum, minimum, and average temperature, temperature departure from normal, dew point temperature, average station pressure, ceiling, visibility, weather type, wet bulb temperature, relative humidity, degree days (heating and cooling), daily precipitation, average wind speed, fastest wind speed/direction, sky cover, and occurrences of sunshine, snowfall and snow depth. The source data is global hourly (DSI 3505) which includes a number of quality control checks.

Local Climatological Data (LCD) contains summaries from major airport weather stations that include a daily account of temperature extremes, degree days, precipitation amounts and winds. Also included are the hourly precipitation amounts and abbreviated 3-hourly weather observations. This is the final quality controlled copy and generally has a one to two month time lag. The local climatological data annual file is produced from the National Weather Service (NWS) first and second order stations. These data are contained in the LCD monthly and annual publications. The monthly summaries include maximum, minimum, and average temperature, temperature departure from normal, dew point temperature, average station pressure, ceiling, visibility, weather type, wet bulb temperature, relative humidity, degree days (heating and cooling), daily precipitation, average wind speed, fastest wind speed/direction, sky cover, and occurrences of sunshine, snowfall and snow depth. The annual summary with comparative data contains monthly and annual averages of the above basic climatological data in the meteorological data for the current year section, a table of the normals, means, and extremes of these same data, and sequential table of monthly and annual values of average temperature, total precipitation, total snowfall, and total degree days. Also included is a station location table showing in detail a history of, and relative information about, changes in the locations and exposure of instruments. The NCDC also archives a Preliminary Local Climatological Data manuscript that contains similar information, but is not quality controlled.

The CDNS was published from 1950 - 1980. Monthly and annual editions contain summarized climatological information from the following publications: Local Climatological Data (LCD), Climatological Data (CD), Monthly Climatic Data for the World (MCDW), Storm Data (SD), Mariners Weather Log (MWL), Weatherwise, Weekly Weather and Crop Bulletin (WWCB), Monthly Weather Review (MWR). Data includes a national general summary of weather conditions, observed extremes of temp & precip by states, climatological data by station, heating degree/cooling degree days, flood data and losses, and storm summaries. Upper air data, sunshine and solar radiation data are also summarized. The annual issue each year also contains the year's short rainfall duration statistics, hurricane and typhoon data and storm tracks for various basins, tornado information and long term statistics.

Preliminary Local Climatological Data, recorded since 1970 on Weather Burean Form 1030 and then National Weather Service Form F-6. The preliminary climate data pages consist of 3 parts: Part 1 is the site information including the station location, the month and year of the report, and the latitude and longitude of the station. Part 2 is the daily information which consists of columns of data, with one row of data for each day of the month. The day runs from 0000 to 2359 Local Standard Time (0100 to 0059 Daylight Savings Time). Part 3 of the report (noted as Page 2) is the monthly section which consists of various averages and totals for the month. The forms were submitted to the National Climatic Data Center, where quality control was performed and the data published as Local Climatological Data (LCD).

Supplementary data for studies conducted in the Luquillo Experimental Forest (LEF), eastern Puerto Rico include measurements of temperature, relative humidity and cloud immersion at 30-minute resolution. Temperature and relative humidity were measured at five sites; two primary sites have records from April 2014 to June 2019; other sites have shorter records within that period. From these data, derived values of dew point, vapor pressure deficit (VPD), and evaporative fraction were calculated. Daily 13:00 temperature and VPD gradients with elevation along the forested slope were calculated on days with data from at least 3 of the 5 sites (617, 675, 794, 904 and 1006 m), from April 2014 to November 2018. Cloud immersion frequency data are given for sites having the most complete records (675 m and 1006 m), representing the forested mountain slope near minimum cloud base altitude and the highest elevation in eastern Puerto Rico, respectively. Time-lapse camera images at 30-minute intervals were used to produce a binary series of cloud-immersed or clear conditions in the forest from April 2014 - November 2018. Briefly, contrast, luminance and colorfulness of daytime (color) and nighttime (grayscale) images were analyzed to determine cloud presence at the forested sites (methods in Bassiouni et al., 2017). Daily rainfall data and calculated long-term (27-year) semi-monthly mean rainfall amounts are given for Rio Icacos rain gage (USGS National Water Information System, site 50075000, 2019), for use in calculating departure from long-term mean rainfall in related publications. Also given are calculated data on the frequency of lowest-level cloud base observations below 1006 m altitude, from hourly ceilometer records at Roosevelt Roads, PR located at the coast to the east of the study area (NOAA National Centers for Environmental Information, 2020). These data are supplementary to Scholl et al., 2021. References: Bassiouni, M., Scholl, M. A., Torres-Sanchez, A. J., & Murphy, S. F. (2017).

Annual and monthly averages for precipitation, dew point, dew point depression (DPD), sea level pressure (SLP), average temperature, max temperature (tmax), minimum temperature (tmin), visibility, wind speed, and NOx concentration. Data looks at fog season averages for variables, eg November-March. 'FogData' files includes number of fog days per year (days where visibility < .25 miles for 1 hour) and fog hours per year (hours where visibility < .25 miles). Daily averages were derived from hourly measurements. An daily measurements for all continuous variables were created by averaging measurements taken every 3 hours (0:00, 3:00, 6:00, 9:00, 12:00, 15:00, 18:00, 21:00). 7 of 8 hourly observations were required to calculate daily average. Each variable also includes a percent of measurements available for the month and year in a separate file. 65% of daily averages needed to be available in a month to determine a monthly average. All 5 months reported a monthly average in order to create a yearly average. Fog days and fog hours are episodic, thus 90% of hourly observations needed to be available to create an average.

Data were collected between 2013 and 2022 in a research area of the Everglades known as the Decompartmentalization Physical Model (DPM), a wetland area in the central Everglades that includes canals and levees bordering Water Conservation Area 3A (WCA-3A) to the northwest and Water Conservation Area 3B (WCA-3B) to the southeast. During the study more than ten major controlled flow releases occurred by opening the S-152 culverts on canal L-67A that released experimental high flows through the wetland. Here we present the input measurements and metabolism outcomes at 13 wetland sites in the Everglades using the RiverMET workflow (https://doi.org/10.5066/P9TEBOUR) including details about performance metrics. RiverMET runs a metabolism model, assesses the model performance, and flags and censors final output data. Gross primary productivity (GPP), ecosystem respiration (ER) and the air-water gas exchange rate constant (K600) was modeled using water quality data inputs (dissolved oxygen, specific conductivity, water temperature) and hydrologic data (flow speed and water depth) collected by USGS and pressure data from the National Oceanic and Atmospheric Administration (NOAA, https://www.ncei.noaa.gov/maps/lcd/, data accessed September 2021). The workflows are specifically tailored to use streamMetabolizer (version 0.12.0; https://github.com/USGS-R/streamMetabolizer), a model for one-station calculations of stream metabolism that calculates daily average areal rates of GPP and ER, and the daily average volumetric air-water gas exchange rate constant, K600. Also included with this data release are field data contrasting low and high flow conditions in the Everglades, including data associated with a dual gas tracer test ("Dual Gas Tracer Experiments.xlsx") to confirm metabolism modeling estimates of K600 as well as measurements of bed shear stress ("Bed Shear Stress.xlsx"). More information about the input and output data and the ancillary data are available in the file "Data_Dictionary_Metabolism Data Release.docx". Instructions for running RiverMet, using the data and scripts provided here, can be found in the file readMe.txt.
