EnvoAir Enterprise IAQ

Green and Natural Air 

EnvoAir IAQ Data API instructions:
Note : 
There are 8 air quality domians including "pm25", "co2", "hcho", "temp", "humid", "pm1", "pm10" and "voc" 

1. With no parameter, it will just return the latest data of all air quality domains.

2. With specific air quality domain it will show the latest corresponding data:

3. With specific range of date will show all data between two dates

* note that the date in "dateto" command is excluded from the output data, so the api above will just output data until 2019-Apr-18 23:59:59

4. With specific range of date + specific air quality domain:

5. Only retrieve the last N records:
* 1. the "last" command will override "datefrom" and "dateto" commands.
* 2. the "last" command can be used to retrieve data of current date while you can't do that with "datefrom" and "dateto"

6. Retrieve the last N records + specific air quality domain:

Electric vehicles (EVs) have no tailpipe emissions. Replacing conventional vehicles with EVs can help improve roadside air quality and reduce greenhouse gas emissions. A wider use of EVs also contributes to the development of environmental industries.

This API (in XML format) provides location data (including GPS data, address, etc.) of electric vehicle charging stations in Hong Kong. Please refer to the data dictionary for detail.

Consists of lists of stations with their location information, lat-lon and type of the stations. The data also provide a list of 18 districts in Hong Kong for user's reference.

This data shows the Air Quality Health Index (AQHI) at individual general and roadside Air Quality Monitoring stations for the past 24 hours. It is made available by the Environment Protection Department under the Government of Hong Kong Special Administrative Region (the “Government”) at https://DATA.GOV.HK/ (“DATA.GOV.HK”). The source data is in XML web service and been processed and converted into Esri File Geodatabase format and then uploaded to Esri’s ArcGIS Online platform for sharing and reference purpose. The objectives are to facilitate our Hong Kong ArcGIS Online users to use the data in a spatial ready format and save their data conversion effort.

Bauhinia Genome HK

Included here for access is data from Hong Kong’s first emblematic genome project: BauhiniaGenome. Hong Kong’s emblem is the beautiful Bauhinia blakeana flower and appears on our flag and currency. What many people may not know is that it is a sterile hybrid, and how and why it ended up in Hong Kong is shrouded in mystery.

By bringing together the emblematic and mysterious Bauhinia flower and the power and knowledge of genome technology, we can build a bridge between science and community— enlightening our understanding of this plant’s interesting biology and informing and educating the public about this exciting and rapidly advancing field.

To build such a collaborative endeavor, we have launched the first Hong Kong genome project through which we will sequence the genome of the Hong Kong emblem to better understand where it came from; train local students to assemble and analyse the data — crucial skills needed for this field to advance; and engage the public through local pride.

The data presented here are four transcriptome datasets: leaf and flower data from Bauhinia blakeana as well as leaf transcriptomes from the most likely parent species Bauhinia purpurea and Bauhinia variegata. Specimens were collected in Hong Kong, and sequenced at the laboratories of BGI Hong Kong using the Illumina HiSeq 4000 platform. RNA was extracted using protocols available at (see: These data are made available here for analysis and the open-source teaching of transcriptomics analysis.

Chinese Crocodile Lizard Genome

The Chinese crocodile lizard, Shinisaurus crocodilurus, is the only living representative of the monotypic family Shinisauridae under the order Squamata. It is an obligate semi-aquatic, viviparous, diurnal species restricted to specific portions of mountainous locations in southwestern China and northeastern Vietnam. However, in the past several decades, this species has undergone a rapid decrease in population size due to illegal poaching and habitat disruption, making this unique reptile species endangered and listed in CITES Appendix II since 1990. A proposal to uplist it to Appendix I was passed at the CITES CoP17 in 2016.

To promote the conservation of this species, we sequenced the genome of a male Chinese crocodile lizard using a whole-genome shotgun strategy on the Illumina HiSeq 2000 platform. In total, we generated ~291Gb raw sequencing data (149X depth) from 13 libraries with insert sizes ranging from 250 bp to 40 kb. After filtering for PCR-duplicated and low-quality reads, ~137 Gb clean data (70X depth) were obtained for genome assembly. We yielded a draft genome assembly with a total length of 2.24 Gb and an N50 scaffold size of 1.47 Mb. The assembled genome was predicted to contain 20,150 protein-coding genes and up to 1,114 Mb (49.6%) of repetitive elements. 

The genomic resource of the Chinese crocodile lizard will contribute to deciphering the biology of this organism and provides an essential tool for conservation efforts. It also provides a valuable resource for future study of squamate evolution.
